Aerobic and anaerobic respiration Aerobic respiration Respiration using oxygen to break down food molecules is called aerobic respiration.
Anaerobic respiration Most organisms cannot respire without oxygen but some organisms and tissues can continue to respire if the oxygen runs out. This table compares aerobic and anaerobic respiration: Aerobic respiration Anaerobic respiration Oxygen Present Absent or in short supply. Oxidation of glucose Complete Incomplete. All of the energy available from glucose is not released.
Reactants of respiration Glucose and oxygen Glucose. Yeast - ethanol and carbon dioxide and ATP. Some plants - ethanol and carbon dioxide and ATP.
Absent or in short supply. Glucose and oxygen. These organisms and tissues use the process of anaerobic respiration. Human muscle can respire anaerobically for short periods of time — even though the process is relatively inefficient, it's better to continue respiring and be able to run away from danger — or run a race.
The glucose in muscle is converted to lactic acid :. Some plants, and some fungi such as yeast can respire anaerobically — it's preferable to release less energy but remain alive. Glucose in yeast cells is converted to carbon dioxide and ethanol , which we refer to simply as 'alcohol':. Anaerobic respiration occurs only in the cytoplasm of cells. Aerobic and anaerobic respiration compared:.
