In a mitochondrion,if the matrix ATP concentration is high and there is no proton gradient across the inner mitochondrial membrane to generate a proton-motive force,then what might you expect to occur?
A)ATP synthase will increase the rate of ATP synthesis.
B)ATP synthase will synthesize ATP and pump protons into the intermembrane space.
C)ATP synthase will hydrolyze ATP and pump protons into the intermembrane space.
D)ATP synthase will hydrolyze ATP and pump protons into the matrix.

Quizplus · Accepted Answer

ATP synthase can operate in reverse, using the energy from ATP hydrolysis to pump protons into the intermembrane space, thereby establishing a proton gradient when the ATP concentration in the matrix is high and there is no existing proton gradient. This helps in maintaining the proton-motive force necessary for various cellular processes.
