Unformatted text preview: ctures are not organelles (they have no function), but are sometimes called “inclusions.” (storage structures in cells that serve no metabolic fxn) Mitochondria have an outer membrane and an inner, highly folded membrane with the respiratory proteins. Major functions of mitochondria are ATP production via aerobic respiration, lipid metabolism, and control of a specific, important type of cell death called apoptosis. (More on apoptosis next week.) cell releases mitochondrial proteins, cell commits suicide - cytoskeleton broken down, along with all organelles, cell shrinks up and dies. 2 membranes. smooth outer membrane and inner highly folded membrane. inner membrane studded with protein complexes involved in e- transport system! Note the very distinctive appearance of mitochondria with the TEM. Fig. 2-20a The numerous eosinophilic “dots” seen in cell cytoplasm by the LM with H&E are often mitochondria (as seen here on left) or by histochemistry using a citric acid cycle enzyme. At right are shown many mitochondria (...
