Detailed explanation-1: -Oxidation and Reduction Reduction is when a molecule gains electrons, such as when NAD+ gains the electrons from a hydride to become NADH. In this case, we say that NAD+ has been reduced to NADH. Oxidation is when a molecule loses electrons, such as when NADH loses its hydride to become NAD+.
Detailed explanation-2: -Electron Transport System (ETS) and Oxidative Phosphorylation.
Detailed explanation-3: -The conversion of NAD+ to NADH, and vice versa, are essential reactions in creating ATP during what’s called cellular respiration. The food you consume goes through three phases to become energy: glycolysis, the Krebs Cycle, and the electron transport chain.
Detailed explanation-4: -This is a redox reaction. We know that because we have produced a reduced electron carrier (NADH) as a product and NAD+ is a reactant. Where did the electron come from to make NADH? The electron must have come from the other reactant (the carbon compound).
