10.4 Oxidative Phosphorylation Flashcards
1
Q
Electrochemical gradient ETC creates
A
Proton-motive force, generated by ETC across the inner mitochondrial membrane.
The intermembrane space has a higher concentration of
protons than the matrix; this gradient stores energy, which can be used to form ATP via chemiosmotic coupling.
2
Q
ATP Synthase
A
Enzyme, generates ATP from
ADP and an inorganic phosphate (Pi).
3
Q
What is F0 portion?
A
An ion channel, allowing protons to flow down
the gradient from the intermembrane space to the matrix.
4
Q
What is F1 portion?
A
Uses the energy released by the gradient to
phosphorylate ADP into ATP.
5
Q
How much ATP is produced from NADH?
A
25
6
Q
How much ATP is produced from FADH2?
A

8
Q
How much ATP is produced from Citric Acid Cycle?
A
