ATP synthase is able to use the potential energy that originates from_________to produce ATP.
A) the phosphorylation of cytochromes
B) complex I
C) the hydrogen gradient across the inner mitochondrial membrane
D) the sodium gradient across the inner mitochondrial membrane
E) complex IV

Question

Quizplus · Accepted Answer

ATP synthase uses the potential energy from the hydrogen (proton) gradient across the inner mitochondrial membrane to produce ATP. This gradient is established by the electron transport chain, where protons are pumped from the mitochondrial matrix into the intermembrane space, creating a high concentration of protons outside the inner membrane. The flow of protons back into the matrix through ATP synthase drives the synthesis of ATP from ADP and inorganic phosphate.
