WebNAD+ is the oxidizing agent for glycolysis. It is reduced to NADH during the process in the following equation. NAD+ + 2e- + H+ --> NADH In anaerobic respiration, NADH is oxidized through alcohol or lactic acid fermentation to regenerate … WebCells need to get rid of the excess and regenerate NAD +, so pyruvate serves as an electron acceptor, generating lactate and oxidizing NADH to NAD +. Many bacteria use this pathway as a way to complete the NADH/NAD + cycle. You may be familiar with this process from products like sauerkraut and yogurt. mynoc stillwater

WebDec 3, 2024 · Oxidative phosphorylation can be divided into two basic parts, the oxidation steps and the energy-generation events. Oxidation Reactions At the start of the electron transport chain, NADH and FADH2 are present inside the mitochondria, both of which carry high-energy molecules. WebJan 3, 2024 · The end products of electron transport are NAD+, FAD, water and protons. The protons end up outside the mitochondrial matrix because they are pumped across the cristal membrane using the free energy of electron transport. Electron transport and oxidative phosphorylation are summarized in the illustration below.
