Oxidative Phosphorylation

Question 1

Where does this take place?

Answer 1

-inner mitochondrial membrane that is folded into cristae

Question 2

What has been produced so far in the cycle?

Answer 2

• 4 x ATP, 10 x NADH, 2 x FADH, 6 x CO2

Question 3

What are the 4 steps to oxidative phosphorylation?

Answer 3

1. NADH + FADH releases their H ions and electrons
2. electrons produce energy for active transport carrier proteins to move H ions across membrane against grad
3. H ions diffuse back through channel proteins of ATP synthase that regenerate the ATP from ADP + Pi
4. more NADH + FADH are always arriving so the excess bond with oxygen to form water
