Where does ATP synthase get the energy required to drive phosphorylation of ADP?
A) from the flow of protons from the intermembrane space to the matrix through the inner membrane
B) from the flow of protons from the matrix to the intermembrane space through the inner membrane
C) from the flow of protons from the intermembrane space to the matrix through the enzyme

Quizplus · Accepted Answer

ATP synthase utilizes the energy from the flow of protons (H+) from the intermembrane space to the matrix through the enzyme itself to drive the phosphorylation of ADP to ATP. This process is part of the chemiosmotic mechanism of ATP synthesis in mitochondria and chloroplasts.
