Oxidative phosphorylation is the use of electrons falling from the hydrogen in glucose to the oxygen in a living cell. - Definition & Function, Biological and Biomedical As pyruvate enters the mitochondrion, it is converted into another molecule called Acetyl CoA, which then goes through the second stage of metabolism, known as the Krebs cycle. Then when these hydrogen ions fall back downhill, they do so through protein complexes called ATP synthases. Oxidative phosphorylation occurs in the mitochondria of all animal and plant tissues, and is a coupled process between the oxidation of substrates and production of ATP. * Provide a detailed explanation using detailed vocabulary.
