WebThe mitochondrial outer membrane plays highly important roles in both health and disease. It is not simply a protective cover for the mitochondrial inner membrane plus matrix compartments where the TCA cycle and oxidative phosphorylation take place, but rather is very active, in fact much more active than most investigators realize. WebThe outer membrane is permeable to most ions and metabolites, but the inner membrane of the chloroplast is highly specialised with transport proteins. [4] [5] For example, carbohydrates are transported across the inner envelope membrane by a triose phosphate translocator. [6] darrell mcabee blackwell ok
