The complete conversion of glucose in the presence of oxygen into carbon dioxide and water with release of energy is called

Aerobic respiration is the complete oxidation of glucose in the presence of oxygen, producing carbon dioxide, water, and approximately 38 ATP molecules. It occurs in mitochondria after glycolysis and includes the Krebs cycle and electron transport chain. Anaerobic respiration (B) occurs without oxygen and yields far less energy (2 ATP). Glycolysis (C) is only the first step breaking glucose into pyruvate. Hydrolysis (D) is a general chemical process using water to break bonds, not specific to energy production.
