Oxidative phosphorylation

• Oxidative phosphorylation is the final stage in aerobic respiration, occurring on the mitochondrial inner membrane or the cristae, with enzymes and carrier proteins embedded within them.
• The first three stages of aerobic respiration are glycolysis, which occurs in the cytoplasm, the link reaction that creates acetyl coenzyme a, and the Krebs cycle, which occurs in the mitochondrial matrix.
• Ten reduced nad and two reduced fad are created from one glucose molecule during these three stages.
• Oxidative phosphorylation is a step where most of the ATP is produced, with the exception of the ATP made in the Krebs cycle and glycolysis.
• The three key parts of oxidative phosphorylation are the electron transfer chain, movement of proteins across the cristae or the inner mitochondrial membrane, and catalyzation by ATP synthase.
• Oxidative phosphorylation is an example of chemiosmotic theory, where the electrons from the electron transport chain are used to catalyze the reaction of adp plus pi/2 make ATP.
• The role of oxygen in oxidative phosphorylation is to accept electrons at the end of the electron transport chain and create water.
• Oxygen is the final electron acceptor in the electron transport chain, and if it didn't accept those electrons, there would be no more electrons move down the chain, protons wouldn't be transported across the membrane, and ATP wouldn't be made.
