Aerobic Glycolysis vs. Anaerobic Glycolysis — What's the Difference?
Edited by Tayyaba Rehman — By Fiza Rafique — Published on January 3, 2024
Aerobic glycolysis requires oxygen and produces more energy, while anaerobic glycolysis occurs without oxygen but generates less energy.

Key Differences
Aerobic glycolysis occurs in the presence of oxygen, efficiently producing energy. Anaerobic glycolysis functions without oxygen, yielding less ATP.
During aerobic glycolysis, glucose breakdown is complete. In contrast, anaerobic glycolysis partially breaks down glucose.
Aerobic glycolysis produces CO2 and water as byproducts. Anaerobic glycolysis results in lactic acid formation.
Aerobic glycolysis is a longer process, occurring in mitochondria. Anaerobic glycolysis is a quick reaction, taking place in the cytoplasm.
