Oxidative phosphorylation is the final stage of cellular respiration, producing ATP through a series of redox reactions in the electron transport chain.
Khan Academy provides an overview of the steps involved in cellular respiration, including glycolysis, pyruvate oxidation, the citric acid cycle, and oxidative phosphorylation.
In oxidative phosphorylation, FADH 2 is involved. (Choice D) This is an example of oxidative phosphorylation: Phosphoenolpyruvate + ADP → ATP + Pyruvate
When the H + flow back down their gradient, they pass through an enzyme called ATP synthase, driving synthesis of ATP. This process is known as oxidative phosphorylation. The diagram below shows examples of oxidative and substrate-level phosphorylation.
