Oxidative Phosphorylation coupled with Aerobic and Anaerobic

Oxidative phosphorylation works by using energy-releasing chemical reactions to drive energy-requiring reactions. The two sets of reactions are said to be coupled. This means one cannot occur without the other. The chain of redox reactions driving the flow of electrons through the electron transport chain, from electron donors such as NADH to electron acceptors such as oxygen and hydrogen (protons), is an exergonic process – it releases energy, whereas the synthesis of A… WebIn prokaryotes, the total ATP production from both oxidative phosphorylation and substrate-level phosphorylation can be as high as 38 ATP per molecule of glucose. In eukaryotes, the ATP production is slightly lower because of the energy cost of transporting pyruvate into mitochondria: a common figure is 36 ATP per molecule of glucose. long kitchen tables for saleWebRecall that the production of ATP using the process of chemiosmosis in mitochondria is called oxidative phosphorylation.
