A proton gradient across the mitochondrial inner membrane is the result of B) more protons in the intermembrane space of the mitochondrial than in the mitochondrial matrix. The proton gradient is created by pumping hydrogen out of the matrix space. Since hydrogen is pumped through ATP synthase, its enzymatic activity allows synthesis of ATP.
