ETC and Oxidative Phosphorylation Flashcards
1
Q
What are the four major complexes in the ETC?
A
NADH oxidoreductase, succinate dehydrogenase, cytochrome b/c and cytochrome oxidase
2
Q
How does the ETC cause a proton gradient?
A
The flow of electrons down the ETC drives H+ ions across the mitochondrial membrane into the jntermembrane space which causes an energy potential.
3
Q
How is the proton gradient in the ETC used to generate ATP?
A
When the gradient is reversed energy is released
4
Q
What is respiratory control?
A
The regulation of the rates of the RTC and oxidative phosphorylation by ADP levels
5
Q
What three other processes do proton gradients power?
A
Transport processes, chem praxis and some organisms
