In the final stage of glucose oxidation, high-energy electrons are passed in a controlled series of steps to lower-energy-level electron carriers, with a small amount of energy released at each step to form ATP. This phase of aerobic respiration is known as:

The citric acid cycle

Anaerobic fermentation

The tricarboxylic acid cycle

Oxidative phosphorylation

The Krebs cycle

Correct Answer

Oxidative phosphorylation

Explanation

Oxidative phosphorylation is the process by which energy released as electrons move through the electron transport chain is used to attach phosphate groups to ADP, forming ATP.
