Detailed explanation-1: -The inner membrane of mitochondria is organized in two morphologically distinct domains, the inner boundary membrane (IBM) and the cristae membrane (CM), which are connected by narrow, tubular cristae junctions.
Detailed explanation-2: -The inner membrane allows for the transport of hydrogen ions into the inter-membrane space, while the outer mitochondrial membrane prevents their escape. The two membranes working in conjunction build up a lot of potential energy in the form of the charge possessed by the ions within the inter-membrane space.
Detailed explanation-3: -The inner mitochondrial membrane contains many copies of a protein called the F0F1ATPase. This is also called ATP synthase. It consists of two parts: the F0 component spans the membrane and provides a channel for protons to move into the matrix from the intermembrane space.
