Question

ATP synthase is the protein complex that__________.

A. transfers electrons to oxygen in the final step of the respiratory chain.
B. rotates when ATP is hydrolyzed in the mitochondrial matrix.
C. captures the potential energy of the proton gradient in the intermembrane space as the chemical energy in phosphate bonds of ATP.
D. transfers electrons from the inner mitochondrial space to the mitochondrial matrix. E. creates a proton-motive force when glucose is oxidized.

Answer 1

C. captures the potential energy of the proton gradient in the intermembrane space as the chemical energy in phosphate bonds of ATP.

Step-by-step explanation:

ATP Synthase uses the energy of an existing proton gradient to power the production of ATP. This process is known as CHEMIOSMOSIS.
