Biochemistry
Aerobic
Requiring or occurring in the presence of oxygen. Aerobic respiration is the most efficient way to extract energy from food.
Biological Context
Aerobic respiration in mitochondria produces about 36-38 ATP per glucose molecule, compared to only 2 from anaerobic fermentation. Most complex organisms are obligate aerobes. Aerobic conditions in soil and water support decomposition and nutrient cycling.
