Oxidative phosphorylation and the electron transport chain | Khan Academy

[@emanuelsahr]

I love Biochemistry and Biology in general. It gets a lot better when someone explains it clearly. Love science man

[@DomTheGreat100]

I don't get why professor get paid so much to teach so little while this guy just taught me everything in 15mins...

[@bluesmanshoes]

Cause he or she in the first place is a researcher, not a teacher.

[@veksu9]

thats right, good researcher doesn't mean good teacher. I think that some people have forgotten that.

[@goclbert]

They typically don't get paid "so much"

[@denizoncu4345]

@@DahenKike You are the one who is pretty st*pid here. Don't you know how to respect to teachers? Oh sorry, I mean "Medicine teachers(!)."

Love how passionate he gets about the ATPase as a rotary motor lmao

[@Robert4865]

Well it is cool tbh; the smallest motor in the known universe

[@toniodivichi5749]

"It's not some abstract thing that's separate from your reality!" . When he says stuff like that it makes the lesson memorable XD.

[@adnertga6559]

If only more teachers were that passionate.

if only i could go and get the government to send my uni payments to you.. thanks for my first year biochemistry module!

Thank you so much. Seriously I am impressed by how I learn more with a 15 minute video, than what I learned in a whole semester of biochemistry in med school.

wow, your enthusiasm made me actually enjoy biochem... :D keep it up

[@randombadger41]

Khan Academy you should produce the big flow diagrams present on the videos (like this one) as downloadable PDFs for us to download, they're really useful!

[@SamuraiMasenko]

+randombadger41 Seconded. Sometimes I just recreate them myself, but it's a stupid amount of work.

[@DragonBornGirl50]

I was about to say this actually I want the whole thing in pdf so i can look it over its so nice

[@ReezahNaroth]

I agree!

[@bryced2846]

Well actually there r a few images like these (with white background so u can print it) on his khan academy app or website. :D

[@kat1577]

I love y'all. I was becoming extremely frustrated, but FINALLY, a video that held my hand !!!😊

[@bonniebarbour5076]

Which of the videos directly precedes this particular one? Specifically which one explains the output of the 4 ATPs, 10 NADHs & 2 QHs as shown on the top right of this presentation in purple. I might assume if I was to watch them in order it would be 1) Steps of Glycolysis, 2) Krebs/Citric Acid Cycle, 3) Oxidative Phosphorylation 4) Electron Transport Chain ???????? Thanks.

[@HEXONE]

So basically ETS and oxidative photophosphorylation are one and the same or The oxidative photophosphorylation is just a part of the ETS!! Thanks KHAN ACADEMY!!

[@SL-oh8rq]

this is like my life fucking saver. actually, all of his videos are. this dude is fucking god

Where was this when I was studying for my biochemistry final?!?!

[@Alex-ij1km]

+Media Luna hahaha ikr

[@georgeklucsarjr1988]

Nice demonstration. 2 questions 1) how does the matrix acquire all of those protons ( that later get transported )? 2) how does the oxygen molecule get inside the matrix?

[@kellygiles6217]

Thank you so much Mr. Khan, my lord, savior, and personal baby jesus. May you be blessed with all of the ATP synthases that you could ever want. (I could tell you really love them!)

In the cell does it take ATP to get ATP in this process?

Where does the two electrons come from? NADH -> NAD+ + H+ (+ 2e)

[@markoconnell804]

Does the electron transport chain require ATP to make it?

Whats the difference between oxidative phosphorylation and electron transport chain?

[@haroonrashid4152]

yup same question here:-?

[@saadrehman362]

oxidative phosphorylation Is the process of creating ATP by reducing oxygen. Oxidative phosphorylation occurs on the electron transport chain. So basically, the ETC is the site of oxidative phosphorylation.

[@dottiEpre]

Thank you.

[@gedy4612]

could you solve a case were these is something wrong with the mitochondrian which leads to a person not walking, sitting, talking. Basically entire body does not function. I am looking for someone who can look at this case because they can not find what the problem is! they now the 'pump' in the mitochondrian is not working.. but they do not know why. We can not proceed if this is not find! please any help means the world

[@raahulraam5456]

actually in the electron transport chain ,the H+ ions used in the reaction for oxidation of O2 is one and the same reaction here with 2H+ ions is two...can i get any explaination

just Awesome

[@soonear9185]

Loved how he explained "hydrogen proton" without even thinking about it... like thats not enough information that someone has to check the textbook for. Lol

[@Krypton92546]

They prepare first

[@chakibkhoury9103]

what program is this?

[@MrBeachwaves]

Can someone please explain why the oxidation of coenzymes such as NADH causes hydrogen protons to be pumped into intermembrane space? Thanks!

[@spartacus871]

During oxidative phosphorylation, what is the net ATP production, assuming two ATP molecules are consumed during the process?

[@TonyTigerTonyTiger]

About 28 ATP are produced by oxidative phosphorylation per starting glucose. Adding the 2 net ATP from glycolysis and the equivalent of 2 ATP from the citric acid cycle, the total ATP per glucose for all of cellular respiration is about 32 ATP. The older values of 36 ATP or 38 ATP are now outdated.

[@sivashankarkonda7053]

Awesome

[@taiwooladimeji5968]

IS Oxidative phosphorylation and the electron transport chain the same?

[@Lydsybitsy]

Taiwo oladimeji yes

I'm going into the Sixth Grade and I need you help. Well in summer your supposed to do a math packet. I'm on basically the last page but I have no idea how to do this one problem. This is is " 10= 2/3 x _____ and you have to answer the blank. If you can please make a video on how to do it. In. A couple days it's going to be school and I have to finish it. Thanks :)

[@saunyboy123]

+Antonella Melillo Hi Antonella, First set up the equation where x is the unknown number to find: 10=2/3x Next, multiply both sides by 3: 30=2x and now finally divide both sides by 2: 15=x and so 15 is your answer :)

[@antonellamelillo3556]

+Saunyboy omg thank you so much :)

[@antonellamelillo3556]

[@saunyboy123]

Antonella Melillo No problem, happy to help!

[@keurinrin16]

What is H20 for? And what makes oxygen as the final acceptor?😸😸

[@jamesgoodman5102]

+Krin rin H2O is a byproduct of cellular respiration. O2 is the final acceptor because it's the last chemical species to accept the electrons, after the complexes. When it accepts the electrons, it becomes water.

What course are you doing?

[@veksu9]

You probably hate this cuz u dont understand. If you learn it, it becomes easy and pleasuring.

[@tunneltrance]

maybe you just have a weak biology foundation? that's what I found out, my lack of simple biology knowledge (as a chemistry major) made biochem more annoying then it otherwise would be. But it's a cool subject if your objective about it
