Getting Oxygen: Myoglobin vs. Hemoglobin

[@graceusa3942]

This teaching is so good. I love it. You helped with my learning about Hemoglobin and myoglobin so much. Thanks a million.

[@Penguinprof]

You're very welcome! Glad it was helpful.

[@andrzejszydermann5914]

Informative, to the point, concise - thank you for this!

[@happyday2go]

Penguin Professor, you are gifted with an amazing voice that helps me listen to this information much better than the professor in school. It just made me think more about how there are many other factors that can make teaching better.

[@alexmamoga]

Literally one of the best videos I've seen so far! Thank you!

[@dialed.in.autohaus]

love the conciseness and how well explained the concepts were. Thank you!

[@Penguinprof]

+Timsterfied Thank you for watching! I'm so glad you found it helpful.

[@gabicuriano1262]

Very clear and straight to the point. The animation was a great idea. It helped me understand a lot more. Thank you so much!!

[@mavislove2705]

This is a super good and clear explanation! Didnt understand the bohr shift until i listened to your video. Thanks🙏🏽🙏🏽☺️👍🏼

[@sl2329]

I love your presentation style, good voice inflection and organization. Your points were very clear.

[@annacho6462]

Learning this in biochem rn. Thank you for your video! Helped me understand this concept well

[@Samara8552]

wow its amazing how simple you made this thank you. My professor did NOT explain it like this and made it ridiculous to understand in biochem. I wish you were teaching my class! I dont see whats wrong with explaining things in a simple way if possible!

[@rlafhaks]

Thank You PenguinProf That was extremely clear and helpful I actually understood everything in the first go

[@waikesaraged.7517]

This video was very helpful. Thanks much for your clear explanation helps me to understand the binding affinity between the Hb and Mb ... Once again thank you so much...

[@DreamBelief]

Thanks so much. I tried looking up a few explanation of this and yours explained everything in a straight forward and order manner.

[@stevo36ify]

Excellent stuff, prof! Thanks! Do you ever do videos pertaining to exercise physiology, such as VO2 max, lactate threshold, ventilatory threshold, or anaerobic threshold? Or perhaps energy systems? Thanks again!

[@HxAlabdulla]

great.. your sound is clear

[@lamhoyin166]

i love the way that u explain some ideas it made me understand more

[@DrMungli]

Great video professor, I like your videos which are informative and great source of learning..

[@jiangfengchu5890]

Great video, just wish you discussed the implications of the Bohr effect and how it causes release of oxygen in oxygen-deficient tissues

[@isaiahmoger3225]

beautiful. thanks much! i love the slider demo at the end! Another term which helped me understand the topic more fully was "homotropic" which helps explain the sigmoidal shape of the hemoglobin curve. homotropic ~"attracting the same"~ is that characteristic which makes the second and third O2's easier to bond. I can't explain it too well but maybe thePenguinProf can!

[@MarioLoeraJrMALJR]

BRILLIANT! Great presentation. Thank you!!

[@LindseyLovesSinging]

Thank you for the straightforward and informative presentation! It has helped cement some concepts I'm learning in Biochemistry!

[@Fluviblue]

this was really helpful to me. thank you for posting!

[@ericksc1924]

Thanks so much! Learning about the lungs in Exercise Physiology, and this rocks!

[@nastyNizzle34]

well done. the software is very helpful in your demonstration!! thank u

[@shuroukzakiaazzo6702]

the best explanation ever. Thank you!

[@ch.praveenkumar3771]

awesome graphical explanation......

[@mohammedfaiq5620]

Thank you so much for your explanation and make it easy to understand

[@Penguinprof]

+mohammed faiq I'm so glad to hear - thanks for watching!

[@tracykovaleski7128]

I love your videos :) Thanks for sharing your love of learning and teaching. I have an idea for this video.. With your taxi cab analogy you could teach about the Bohr and Haldane effects. With the Bohr effect- the taxi drops off oxygen and picks up CO2 (if I understand it correctly of course ;)).

[@nyclear]

increasing pO2 is really just saying/ a measurable way to say you are adding oxygen? More O2 means increase in pO2? And is there a part 2 video that describes what the physiological advantage of Hemoglobin's Borr shift and the advantage of Myoglobin having no Borr shift? Thanks. I just want to relate this to practical human physiology

[@farahkaragholi]

you made my life easier ! thanks

[@sarooomar1D]

Thank youuu very much I found this SUPER HELPFUL ❤️🙏🏽

[@meetan-]

Good presentation very useful thanks. ...

[@KJKP]

Would be interesting to see saturation down around pH 3.... a condition highly correlated with cancer.

[@lizmay3]

Very nicely done! Can you explain what the big physiologic advantage is when the Bohr effect occurs? I could not understand why a decrease in pH that leads to a decrease in oxygen carrying capacity would be an advantage. Thanks1

[@Penguinprof]

A drop in pH is usually due to an increase in anaerobic metabolism; when that occurs, the cells need more O2, so the increased unloading by Hb is of great benefit.

[@ivanpanic63]

Can u please tell me how to tell difference betwen *myoglobin* and *blood* ? I need to know when i eat the meat how to prepare them. Thanks in advance,exelent video :)

[@melaniiiee]

I'm from Germany and we have to explain the exact same graph as a homework, so thank you for your great video, because I didn't really find a video in german about it xd

[@memorycardslut]

kickass graph!!!

[@aleynacabuk7352]

thank you teacher it was wonderful

[@1490063]

made it very clear. thanks

[@shiilovesdogs]

Hi thank you so much for your videos they are so helpful! I'm currently taking biochemistry and I was wondering if you plz cover more topics for that course? :)

[@nursyafinazhazahar3387]

Thank you so much!!!!!!!!!!!!!!! This video really helps me :D May God bless ya!

[@ivansilva7631]

Awesome. Thanks for the simple and clear explanation. :-)

[@baburo101]

thnks... more vids plz

[@Mayowa1994]

Yea. You’re amazing

[@arielasturias141]

Thank you!

[@nehap4769]

Amazing. Thanks !

[@Mr10minutes]

Can we increase the amount of hemoglogine and myoglobine like marine mammals somehow ?

[@lizmay3]

Thanks!

[@Mr10minutes]

If the PH goes higher and make your blood more Alkaline, does hemoglobine will bond even more with the oxygen ?

[@LegeFles]

Blue-Immersion Freediving probably, because there is competition between H+ and O2

[@Isteshhad]

amazing.

[@Inspireflyer]

I normally don't like things because I'm too lazy to press the like button, but when I saw those cartoons, I immediately liked.

[@Penguinprof]

+IamSidetracked Too lazy to press the LIKE button had me laughing out loud! Thanks for watching (and for the heavy finger lifting involved!!!) :)

[@qlagertha6814]

Thankyou So so muchhh❤❤❤❤

[@Penguinprof]

You're so so welcome 😊

[@criiistiiihellooo]

LOVE THE VOICE :D

[@Olenka79]

Just saw my blood test about my Myoglobin being high, can you please explain it?

[@Penguinprof]

I cannot provide medical guidance here - please visit a site like the National Library of Medicine for easy to understand explanations of medical tests and what results can mean. medlineplus.gov/ency/article/003663.htm

[@sospeterkidasso8826]

Woow amaizing !

[@MyBikEtube]

Extra Like for being a LOST fan. caught the signature sound towards the end of the video.

[@Jumboo364]

Can you come teach my biochem class at the university of utah ;) Thank you!

[@kishorekumaraindala1587]

tq...

[@lennardschlor3183]

Why is Myoglobin in muscels more effective than Hemoglobin?

[@Penguinprof]

It isn't more effective - it's just different; Mb has a higher binding affinity at low PO2s (due to structure) and it is not pH sensitive (again, due to structure).

[@ryu235]

love it

[@Penguinprof]

I'm so glad it was helpful!

[@pinkymixology4965]

I hate organic chemistry. The head of the department said women shouldn't be scientists because they are "too emotional" and even though I recorded him saying that, he had tenure, so the University SUNY Albany did NOTHING

[@nupurg1234]

I LOVE YOU SO MUCH THANKS OMFG

[@Penguinprof]

THANK YOU SO MUCH!!!! I LOVE YOU TOO!

[@dacosta5010]

Why can't you be my Bio Chem Professor?

Unfortunately boring!
