Metabolism Problem Set

Problem 17: ATP synthase

ATP synthase can produce ATP using as a direct energy source:

A. energy from the conversion of glucose to pyruvate

B. energy from the oxidation of pyruvate producing CO2 and H20

C. energy from a proton gradient established in mitochondria

The electrons from from NADH and FADH2 flow through the electron transport chain in the inner mitochondrial membrane generating a H+ buildup in the inner membrane space. This proton gradient (gradient of H+) flowing through the membrane enzyme complex ATP synthetase is the direct energy source for producing ATP.

D. energy derived from the breakdown of NADH and FADH2

E. energy from the metabolism of amino acids
