I understand why everything is happening and i also love the example you give, the analogies.

1. Would chemiosmosis be another name for phosphorylation oxidation? becuase i don't understand that little bit.

2.In the beginning u said we needed 38 atp but my teacher said 36...but we only made 34...and same with the nadh2...my teacher said 6 not 10. so i'm just confused between the # 's ...but everything else was perfect i love the way u teach! it's makes me so intrested! Thank you so much!!!

Yes; chemiosmosis is associated with "Oxidative Phosphorylation" -- the movement of "hot-potato" hydrogens. I did not speak about the details of this in the posted Youtube Video. The "hot-potato" hydrogens are passed from one coenzyme to the next into the outer compartment of the mitochondria. Then the "hot-potato" hydrogens flow "down-hill" (down the concentration gradient) into the inner compartment. As the "hot-potato" hydrogen flow downhill, it releases energy which is used to make ATP.

[professorfink]

Regarding the total number of ATPs generated: Different cells generate slightly different numbers of ATP. Furthermore, 2 ATPs are "used-up" when the pyruvate sugars (pyruvic acid) are transported into the mitochondria.

Obviously, learn the number of ATPs that your own Teacher tells you.

Good Luck!

YAY! Thank you so much, now I can impress my teacher. You actually made me like biology, which is huge because just today I considered dropping the class after I failed a test. You explain everything so well with your analogies! :]

And it's hot!

[zamoraDD]

After looking though several videos I was about to give up. You gave the best explanation of them all. You are truly a talented teacher please continue making videos.

[CatKitify]

Very helpful thank you

[code3kc]

Dear Lord. I just spent the last few hours trying to figure out the finer details of this whole process, like where the Hydrogens and electrons go and just exactly how the ATP is actually made. You just explained it perfectly in 6 minutes. To say thank you would be an understatement, but THANK YOU

[newonthesite1]

It has simplified everything for me.

this saved my life today!!!!

[Samsamros]

i wish i had a teacher like that... amazingly explained!

[roxie2003]

I actually get it now! Thanks Professor Fink!

[hemyanable]

wow , so did that change or something over the years and they discovered the ATP synthase that kind of spins like a turbine to bind the ADP to a P group using the energy released from the moving of the electrons from one co-enzym to the other ..><?

Thank you so much for your time in making this video. I understand the processes involved in cellular respiration. Things my own teacher was unable to teach well. I wish you the best.
