Aproton gradient across the mitochondrial inner membrane is a requisite for the synthesis of atp. what contributes to the creation of this proton gradient?

more protons in the inter membrane space of the mitochondrial than in the mitochondrial matrix.

Choices are:
a. more protons in the mitochondrial matrix than in the inter membrane space of the mitochondrial.
 b. more protons in the inter membrane space of the mitochondrial than in the mitochondrial matrix.
 c. equal number of protons in the mitochondrial matrix and the inter membrane space of the mitochondrial.

That is the right answer, b.
