Document Summary
Electron transport chain takes place in cristae membrane. Cell respiration has 2 phases: anaerobic and aerobic. Series of oxidative reactions cells gradually release energy from glucose, transferring it to molecules of atp (adenosine triphosphate) Energy from atp becomes available for cellular activities. Ex. contracting muscles, passing an impulse, pumping ions by active transport. C6h12o6 + 6o2 6co2 + 6h2o + energy. Special high-energy molecule that stores energy for immediate use in the cell. Adenosine + 3 phosphates removing 1 phosphate = more stable and lower energy molecule. Energy is released when atp converts to adp the energy released is use to add a phosphate to adp to make atp. 2 membranes: an outer membrane and an inner cristae membrane that is folded inner membrane divides mitochondrion into 2 internal compartments. No oxygen anaerobic; glycolysis is followed by fermentation or lactic acid fermentation. Oxygen aerobic; glycolysis is followed by krebs, electron transport, and chemiosmosis.
