Cellular respiration is essentially what type of process?

Explanation

Cellular respiration is a redox (reduction-oxidation) process. Redox reactions involve the transfer of electrons from one molecule to another.During cellular respiration, there are several redox reactions occurring, as electrons are transferred from glucose (or other organic molecules) to oxygen. The process involves the oxidation of glucose (and other fuel molecules) and the reduction of oxygen.In glycolysis, glucose is partially oxidized, resulting in the formation of two molecules of pyruvate. During this process, NAD+ (nicotinamide adenine dinucleotide) is reduced to NADH by accepting electrons from glucose.In the subsequent stages of the citric acid cycle and the electron transport chain, further oxidation of fuel molecules occurs. NADH and another electron carrier, FADH2 (derived from FAD), donate their electrons to the electron transport chain. The electrons are then passed through a series of protein complexes in the inner mitochondrial membrane, ultimately leading to the reduction of molecular oxygen (O2) to form water (H2O).
