Cellular Respiration Part 3: The Electron Transport Chain and Oxidative Phosphorylation

The trilogy is finally concluded! And with a bang, no less, as this final stage of cellular respiration is the one that provides the big energy payoff for the cell. Let's learn about how the products of the Citric Acid cycle go on to the electron transport chain to facilitate reactions that will generate a proton gradient suitable for powering ATP synthase, one of the most fascinating proteins in the body.

If only these presentations had been available 40 years ago. I struggled with learning these topics in my late teens. Thanks Dave. Great work!

Absolutely phenomenal summary. My textbook is great at the nitty gritty details, but I was getting over-whelmed and needed a reminder of the big picture. This is exactly the type of supplemental material I've been looking for, definitely going to subscribe. Thank you so much for the hard work and brilliant explanation!

i've been STRESSING over this content bc i have an exam coming up but being able to see the big picture so clearly and concisely has helped me be able to get into the nitty gritty details and still understand what's going on. actual lifesaver!!

I owe my entire college degree to this dude

[chlowong]

Thank you. This made me realise how bad my notes were at explaining respiration. Godsend.

I need to thank you, Dr. Dave but especially a big thanks go to your trillions of enzymes that helped make this possible.

I love how he avoided saying powerhouse. Similar to Kyle Hill saying "sweater of space time" in place of fabric.

You have to admit nature is pretty elegant.

Thanks Professor Dave! Have my final for Bio today and you made it easier to remember this stuff! I appreciate all your hard work!

One again my hats off PROFESSOR DAVE!! I think your 3 PART series on CELLULAR RESPIRATION are TOP NOTCH and I am surprised quite sincerely that these dont have one million views each by now!!

I have listened to MANY different CELLULAR RESPIRATION videos and yours is the clearest and your GRAPHICS and chemical formulas are VERY CLEARLY presented and explained!!

Thanks Prof. Dave!!

Professor Dave, my professor waited until 1 day before our final to tell us we were taking the cumulative ACS biochemistry exam. You are saving my life. Thank you.

[JMYaden]

Amazing that only a few elements, forged in stellar furnaces, are arranged into different structures and drive all these processes. Thank you for creating this content, Professor Dave!

[therealbossprogrammer]

Dave is basically the god of knowledge. You want to learn anything form chemistry to italian, you can come here. I love your vids!

[Jane-jxnr]

Once again, Professor Dave is swooping in to save my finals! 😁

[lostboi]

I'm taking microbiology right now and this is very useful. I'm 38 and I wish this kind of learning was available along time ago.

Dear god thank you I tried teaching myself this for days trying to understand cellular respiration for an exam in my lecture class and no matter what I did I couldn't understand it, it was way too much to take in at once but you explained it so well and the summary of the products from each step was extremely helpful thank you!

[kawanganyirenda]

wow ! Professor Davie. You helped me in my first year am now watching you in Biochemistry in my second year. Thank you so much.. Continue blessing us 🙏

[VinnyMartello]

I appreciate that you used a Buick Nailhed for your "engine" comparison.

[aphrodite]

professor Dave is my very first professor crush! he helped me so much on this THANK YOU PROFESSAHHHH YOU'RE THE BEST!

[marcusm]

Your dynamic animation is suuuuper helpful! Thanks so much!!!
