The folds in the inner membrane of the mitochondria are called cristae. They serve to provide a greater surface area for the proton-pump through which protons pass down their â¦ concentration gradient through ATP synthase to produce ATP in cellular respiration.1 person found this useful.he folds in the inner membrane of the mitochondria are called cristae.

The outer membrane of the mitochondria contains the protein porin. This forms an aqueous channel through which proteins up to 10,000 daltons can pass and go into the intermembrane space. Indeed, the small molecules actually equilibrate between the outer membrane and the cytosol.However, most proteins cannot get into the matrix unless they pass through the inner membrane. This membrane contains cardiolipin which renders it virtually impermeable.ndeed, the small molecules actually equilibrate between the outer membrane and the cytosol.
