The electron transport chain forms a concentration gradient for H+, which diffuses through ATP synthase complexes, producing ____.
A) ATP
B) FAD
C) G3P
D) NADH
E) pyruvate

Question

Quizplus · Accepted Answer

The electron transport chain uses the energy from electrons to pump H+ ions across the mitochondrial membrane, creating a concentration gradient. As H+ ions flow back through ATP synthase, their movement drives the synthesis of ATP from ADP and inorganic phosphate.
