what are the three major pathways by which glucose is catabolized in the human body?
aerobic respiration
anaerobic fermentation
beta oxidation
glycolysis

Explanation:

To determine the correct options, we analyze each:

• Aerobic respiration: Glucose is fully oxidized to \(CO_2\) and \(H_2O\) for energy, a major catabolic pathway.
• Anaerobic fermentation: In oxygen - limited conditions (e.g., muscle), glucose is partially broken down (e.g., to lactic acid), a key pathway.
• Beta oxidation: This is for fatty acid catabolism, not glucose, so it's incorrect.
• Glycolysis: Glucose is broken down to pyruvate, the first step in both aerobic and anaerobic glucose catabolism, a major pathway.

Answer:

A. Aerobic respiration, B. Anaerobic fermentation, D. Glycolysis
