In an electron micrograph of a freeze fractured membrane the bumps seen on the fractured surface of the membrane are?
The inner membrane of the mitochondria is very folded and convoluted. This provides increased surface area for increased reaction rate. In Biology, the faster the reaction rate, the better. Therefore, many processes have evolved traits that allow for increased surface area. Most ATPs (~36) in cell respiration are produced through oxidative phosphorylation in the Electron Transport Chain and chemiosmosis. Both the ETC and ATP synthase (provides for chemiosmosis) are part of the inner mitochondrial membrane…
The cell membrane contains many integral membrane proteins (proteins permanently attached to the surface), over the entire of its surface. These may include integrins, cadherins, desmosomes, clathrin-coated pits, caveolaes, and different structures involved in cell adhesion (the binding of a cell to the membrane surface).
