Aerobic respiration. Definition. noun. (1) A form of cellular respiration that requires oxygen in order to generate energy. (2) The process of generating energy by the full oxidation of nutrients through Krebs cycle where oxygen is the final electron acceptor.Supplement.ith aerobic respiration, glycolysis continues with the Krebs cycle and oxidative phosphorylation. These post-glycolytic reactions occur in the mitochondria in eukaryotic cells, and in the cytoplasm in prokaryotic cells.
Aerobic respiration (with oxygen) can produce 36 to 38 ATP molecules from each glucose molecule. 1  Anaerobic respiration (without oxygen) only allows glycolysis to continue which produces 2 ATP molecules from each glucose molecule. 2  Therefore, aerobic respiration is some 19 times as efficient as anaerobic respiration.
