How does having a folded inner membrane increase the surface area of the mitochondria? When I looked at the illustration, it seemed like having a flat surface would actually maximize the surface area, assuming the outer membrane of the mitochondria retains a constant shape. Is it just the outer membrane folding on the inside? Without which, there would simply be no inner portion of mitochondria? The cerebral cortex does the same thing, but in that case it makes sense, coz' the gyri are convoluted.
