Signal Transduction Pathways

038 - Signal Transduction Pathways.mov
Paul Andersen explains how signal transduction pathways are used by cells to convert chemical messages to cellular action. Epinephrine is used as a sample messenger to trigger the release of glucose from cells in the liver. The G-Protein, adenylyl cyclase, cAMP, and protein kinases are all used as illustrative examples of signal transduction. A review of the concepts is also included.

[@andrewc9099]

This guy is such a boss. Not many people can pull off being Dora and still be cool

[@jenniferwang946]

WHAT 😂

[@animuszen136]

Facts, Dora but with less patronizing, “Now what was this,” cues.

[@codiabshire9385]

I'm on it!

[@marieeem]

LMAO

[@AninomousUser]

I didnt understand this at first until I got towards the end of the video 😆

[@NoyumiAo]

omg I live the Dora the Explorer part, it actually makes sure that I learned something and retained it in my head

[@mrsdiggory3211]

i knowwww! when he said that's right! I felt sooo brilliant and excited to learn more! hahha,

[@user-gm4wl2uj3x]

😂😂😂😂😂

[@ev6564]

Me too!

[@pensandnoodles681]

watched this for high school AP Bio, watching again for college Biochem :) Bozeman never goes out of style.

[@benlinus9]

Pensandnoodles Watching this the class before my AP Bio test, lel

[@SyenPie]

Lmao I'm taking college biochem as well, the textbook overcomplicates the shit out of this topic but this video totally made everything clear...this guy is a damn hero.

[@MeowGF.]

Same! watched this for my MS. Watching it again for my MD lol

[@YesNoMaybeSometimes]

Him: "What's this?" Me: "O_o uhhh.. - " Him: "That's right! Adenalyl cyclase!"

[@palpatine8788]

fr

[@wompusslompus5424]

exactly.

[@chengyoujiang6076]

Eleven years later, still among the best biology videos out there!

[@claurodriguez1864]

You should do that "Dora the Explorer" review in all your videos... it's pretty helpful.

[@johnnylambda6043]

ikr

[@franciscasanchez6311]

Please do a review section on your videos.

[@assumabiru6018]

THE REVIEW PART IS THE BEST I FELT LIKE A GENIOUS AFTER WATCHING THE VIDEO THANK YOU VERY MUCH

[@florac642]

SAME!!! It's amazing!!

[@bera9919]

HAHSXASHHHHAHAHHHAHA SAMEEE!!

[@lisamueller6817]

I don't understand why people in my collage make it difficult to understand such an easy thing. You made it much more simple and interesting. Thank you so much :)

[@GenesisUnkn0wn]

Watching the ending review session and shouting out the wrong answers... I should probably watch the video again.

[@lizusmitadas5577]

lol

[@teflondon199]

Wish more teachers were like this....He basiascally made everything clear in 10 minutes. Our seminar teacher couldn't do it in 1.5 hour

[@nathanielgoglia1268]

forreal!!! my whole class was like wth do we do after he told us its our turn

[@kimberly9119]

if only teachers were paid more, you'd get more qualified candidates

[@sarahholland5980]

An entire Sunday spent trying to understand how tf this worked and all I needed to do was check Bozeman Science. Hate myself and love Bozeman

[@SkopeeProductions]

Hah you just reminded me of last week when I spent 2 hours trying to figure out the difference between "Chromatin" and "Chromosome."

[@madelenefayeho8526]

I love the Dora review parts! They're extremely helpful because repetition, but the silliness and childhood memories make them more memorable. It's Dora for college students! You're the best, Paul!

[@DefineHatespeech]

Who else is watching this right before a Bio test

[@SyenPie]

I'm fucked :)

[@ashleyhuang388]

me 2

[@nathansmith4631]

Yep 😂

[@reikmitsuha1665]

It’s just a quiz for AP Bio, the test is the day after 🙂🚨

[@RidingAGrizzly]

I'm so screwed!!! I don't like this subject, Molecular Biology. I don't understand this subject, Molecular Biology. Now, right before the test, I don't know anything from this subject, Molecular Biology.

[@dantewhite5367]

This guy has free, ad-free content, and he is doing more for me than my teacher who has multiple degrees and gets paid to teach me.

[@meibecky7]

When Bozeman saves your AP bio Grades>>>

[@melikediker5864]

I'm here in 2022 and after 11 years, still this video helps me. Teacher knows his job very well ^-^ Thank you!!

[@imanz7681]

Bozeman and chill?

[@brusquebuttrue589]

Lmao.

[@rdriessen9710]

+Iman Zarrinkoub You just made my day with that comment....

[@meyergulledge]

( ͡° ͜ʖ ͡°)

[@gloria9983]

I am more amused with the 'dora' section than I should be :)

[@ertzor]

this is the first video I've seen from you, but can already tell that you're awesome.

[@MarciBastienSanchez1]

Definitely a gifted teacher! Want to watch all of your videos, thank you for the review!

[@xpinchable]

i loved the dora portion it was hilarious and extremely helpful!

[@WontonSoap]

that dora review party was actually so good

[@robbyschwartz]

Honestly that whole Dora the Explorer bit was SUUUPER helpful!!! Thank you for looking at the screen awkwardly and asking questions on my behalf! Very much appreciated!

[@Agila088]

This is the best cAMP video I've ever witnessed. Thank you Bozeman!

[@bothainah8420]

I absolutely LOVE it when you review and ask questions! such a great teacher. Thank you!

[@Isterbollen]

Just wanted to say you make the best biology videos on the entirety of youtube, thank you!

[@dulanik1997]

I used to watch your videos to get through Ordinary Levels, it's been nearly 8 years, I'm in college and still getting your help whenever needed.

[@neoncrayon8362]

I liked the fact that you simplified the material and presented it with such easy visuals. The Dora part also acts like a revision tool.

[@blythesaunders3124]

I will be having my first exam in med school next week. You make it easier to understand. Thank you so much!

[@user-pp6vb2xp8u]

I have been watching more than 10 videos to understand this path way but non of them helped! till I luckily found this one AMAZING explanation.

[@ttlax19]

You're awesome Mr. Anderson! Currently taking pharmacology and this video provided great insight! Love the guitar example, won't forget it

[@arose19581]

I've been trying to understand this all year without any luck. Its been explained to me dozens of times, but this video made me understand it better.thank you!!!

[@tsunamihan8088]

I have literally been watching your videos throughout the whole year and they have been helping me so much. Thank you for making these videos!! (the dora part was actually really helpful... i remembered it way better when we did that sort of review thing)

[@valerierussell6867]

I used your videos to help teach high school science. But now I am back in university taking sciences again, and I used them to study for my tests! Thanks so much.

[@zainabbaqer4713]

Mr. Andersen, thank you very much. you are one of the best lecturers in the world.

[@emilyd4385]

Your Dora approach helped me pinpoint the parts I was most unsure about. Thank you for a wonderful, thorough video!!

[@JhosethV]

This topic was driving me crazy, thank God I found you right on time. This is truly helpful and intelligible. You just gained a subscriber.

[@AmitFenn]

You boost my confidence with the quiz at the end and your supporting words, man.. :'( You're so nice.. especially when I haven't studied for tomorrow's exam..

[@BallyBoy95]

I love that he actually checks that I've retained the info. with the Dora the Explorer section. Thank you!

[@dominiccezar7514]

I got a first in my exam watching your lectures, you help create the sense of understanding without reading hundreds of books. You're a really good teacher!. Only wish i knew you before i started to panic for my exams.

[@chuuuchaaa9467]

how can people unlike it? i am a chemical engineer and pursuing masters degree in biochemistry and your videos are so amazing. very easy to understand... Thank you so much!

[@Bandtx]

LOL at the Dora the explorer portion

[@MsBloodHeart]

+Bandtx I ended up actually saying the answers out loud lol :)

[@nyusufffff]

That actually was very helpful imo

[@asol9241]

me too lol

[@astridjohnson965]

NinjasHeart Same! It gave me confidence I actually know it

[@SoSexyTrini]

Loved it!!! specially the Dora inspired review...definitely gonna help with finals :)

[@ra_mry3062]

This is my weakest area. Exam is tomorrow. Thank you Mr. Anderson.

[@NateFiasco]

Got a physiology test tomorrow. This really helped. May the science gods be in my favor tomorrow.

[@jlrohrich]

This video was shared by a fellow anesthesia classmate and has helped immensely! Thank you!

[@JSanctum]

I actually liked the last part the most, even though I had a lot of fun with it, that's exactly how I question other classmates. Just fill in the blank to make out the whole picture. Very helpful, great video.

[@anapaulasisa2128]

Omg, I think I love you for making this video. I can't explain how useful this was to me. I loved the Dora review at the end.

[@monasaid1839]

You make it more easy to be memorized when you connected with the amplified guitar sound. Thanks for the video!

[@ChannelTy24]

You are seriously an unbelievable teacher. Thank you so much!

[@jordannahassanali774]

I use to watch this guy when i was in my undergrad just trying to get through with gen chemistry and now here we again, i'm doing my md and watching his videos to help me get through with biochem.

[@heatherpaulson8590]

All of your videos rock (esp this one w/the Hendrix analogy) & they always help clear up complex concepts - keep up the great work.

[@TheDewniz]

Could be on of the best biochemistry videos I have watched before my exams!

[@evelynkolks3864]

mr anderson you have saved not only my ap biology grade but my classmates and all other viewers and we mercifully thank you

[@NomaMPride]

I don't know why I haven't seen this channel earlier. Thank you 🌻

[@tiffanyrago9487]

I just passed my first test in grad school because of you (taking advanced physio). Just wanted to say thank you!!

[@abygailb6023]

The Dora review literally made my day

[@bt6611]

I love the questions at the end! Thanks, Mr. Andersen!

[@DominationofProcrastination]

This guy is my actual savior right now. Bio-chemistry is literally nothing but gibberish to me, and this video was actually able to somewhat explain what the heck signal transduction pathways are. Praise Bozeman!

[@claudekennedy7855]

Its really helpful when you do the "Dora" Q and A thing, you should do it more often.

[@FADILKARIM1]

I love the reviews he did at the end! it really tied everything together:)

[@christine5167]

Got the concept , could not of done it without you thank you

[@Sophicx]

Best/most helpful video I’ve seen on this so far. Thank you.

[@Victoria-rb7wj]

All jokes aside, the dora review is much needed. Hope to see this in other biology videos!

[@jamesphungphol8757]

Thank you from my heart for making this video

[@noone-sr1ps]

The little kid inside me actually clapped when I got the answers right ^_^ Made the learning process a whole lot fun! Love you Bozeman!

[@veslemill]

I'm Norwegian, and I'm up for my final exam in cell biology,and I just have to say a big thank you! Even though I have a norwegian teacher, you explain this in a much better way :-D

[@Cynt12345]

I finally understand this, thank you so much. I didn't quite get the way my professor taught this but you made it so easy to understand and remember.

[@jayfoster4506]

Life saverrrrrr - love bozeman vids especially this one. Made things so simple!!

[@xxblackwhitex]

I know this video is old but I just wanted to thank you still. I'm not very good at reading and understanding but this has helped me so much. I did think that the waiting for us to answer was a little stupid but I caught myself actually saying it out loud. So it works for me!

[@MeaganDoppegieter]

haha the Dora-part is so much fun! you're a great teacher! I study biomedical sciences at university of Amsterdam and I'm always looking for your video's when I don't get a subject.

[@ajaysurya2691]

Fantastic explanation man! Hands down for the way you conveyed it. Respect✌️

[@sallyqdunning]

Thank you! My science teacher loves your videos!

[@missworld2895]

You just made this so much easier for me to understand. Loved the "Dora" part, it really helped me to remember the specific parts. Thanks!!!!

[@55123Swiftfoot]

You several times refer to the G protein-coupled receptor AS the G protein; I believe this is misleading as the subunits themselves are actually the G proteins, and biology teachers and the AP exam will doc you points for not knowing the difference. other than that, great vid!

[@Floopsydabunny]

Oh thanks!!!!

[@elacionjuliemae]

True. G-proteins are the subunits, and the receptor is called g protein-coupled receptor or metabotropic receptor. He's fun to watch though, and he made the complicated process easier to understand. 👍

[@xcaleebur]

thank you, 7-years-ago guys. i was confused too. your comments cleared up my confusion :D

[@laren5768]

My teacher couldnt explain it in 70 mins, you did it in just 9!

[@gracehamilton1034]

Been watching Mr. Anderson since 9th grade AP Bio and still watching him for my intro Bio class in College. Mr. Anderson you rock!!!!

[@OrtenciaP1228]

Wow you are amazing!!! :) Love the part where you stop and ask questions, it's a really good way to participate. Thankx for sharing your knowledge.

[@bjayyne]

Thank you, made it much more simple! I also appreciate the review, made me actually test how much I retained from the video which was all of it by the way!

[@avi5278]

You succeeded in teaching me the learning objectives, while at the same time introducing me to the awkwardness Dora personifies!

[@parasad]

A very good explanation. Clearly clarifies the concept of signal transduction

[@Sullivan858]

Great Explanation of the whole thing man! Much better than any lecture I have attended on it!

[@tobifalola8483]

I didn't study for a test until 8 minutes to it. Sat on the staircase and watched his video on cellular respiration. LOL I slayed that test lmao. THANK YOU BOZEMAN FOR MAKING THE WORLD A BETTER PLACE FOR LAZY PEOPLE LIKE ME!

[@davidrenteria9585]

one week of lectures in just 10 minutes, this guy is just the best . God bless Ya Boozeman! 🔰

[@AnnaLee639]

I learned in 9 minutes what $90 worth of textbooks and an entire graduate level genetics course tried to teach me for an entire semester. Looking forward to my oral examination now. Thanks :)

[@TheKnightrider06]

i can't thank you enough.. this 9:25 min video covered all the things that my bio prof took 30:00 min to make it understandable. Thank you.

[@jsabz3]

this video is god tier. thanku bozeman science

[@reamkamal2545]

Watching it 8 years later and it's still very helpful and amazing 😍😍😍😍❤️❤️❤️❤️

[@carlydrawas119]

This was the best video! I loved the review at the end- really helps the info to stick!

[@revenreplay9713]

His videos have been helping so much in AP bio

[@Shaftell]

this video was so helpful. I combined it with the PenguinProf's video regarding signal transduction and it pretty much summed up three weeks of lecture for me. Perfect.

[@adeoktiviyari1698]

Wow, thank you. Your explanation is incredible and easy to follow. I got hard time to understand this signal transduction principle before, but you made it so simple that even a dummy like me can understand.

[@knorra.1492]

Thank you sooo much! You gave me a better understanding of this concept than the textbook did!

[@warishaghafoor5987]

You totally rock! I mean, your explanation method is just amazing.

[@moniquejohnson9739]

Mr Anderson....you are amazing! Without your collection of videos. Biology this year would have been so much harder! Thanks heaps :)

[@audreyfleck947]

Liked the quiz at the end!

[@matt234111]

Excellent job as always. You are much better than 99% of college professors.

[@amberpickett5659]

Never had more fun at 12 am then a Dora review for ap bio.

[@cocolover26]

Your videos are SO HELPFUL! I think images along with the lecture really help you learn. Thanks!! :)

[@daisyramos6377]

YOU ARE THE BEST. You're better than my Biology teacher thank you for all your videos!!!!!
