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

A

aerobic respiration

B

anaerobic respiration

C

glycolysis

D

hydrolysis

Correct Answer: Option A

Explanation

1. The question asks for the term describing the complete conversion of glucose in the presence of oxygen into carbon dioxide and water with release of energy. 2. This process is the definition of aerobic respiration. It occurs in multiple stages (including glycolysis, Krebs cycle, and oxidative phosphorylation) and yields a significant amount of ATP (energy). 3. Anaerobic respiration occurs in the absence of oxygen and yields less energy. 4. Glycolysis is only the initial stage of breaking down glucose, common to both aerobic and anaerobic pathways. 5. Hydrolysis is a chemical reaction involving water breaking down a compound. 6. Option (A), aerobic respiration, accurately describes the overall process.
