Difference between Aerobic and Anaerobic respiration

Similarities between Aerobic and Anaerobic Respiration

1. Cellular respiration2. Involve in the breakdown of glucose3. Release energy that is stored in the ATP molecules4. Are catalysed by enzyme

Differences between Aerobic and Anaerobic Respiration

Aerobic Respiration Aspects of differences Anaerobic RespirationOxygen is present Availability of oxygen Oxygen is absentComplete oxidation of glucose Oxidation of glucose Incomplete oxidation of glucoseCarbon dioxide, water, and energy

Products of respiration Lactic acid and energy (in muscle) or ethanol, carbon dioxide and energy (in yeast)

38 molecules of ATP Number of ATP molecules released per glucose molecule

2 molecules of ATP

A large amount of energy is released per mole of glucose (2898 KJ)

Amount of energy released per mole of glucose

A small amount of energy is released per mole of glucose, that is 210 kJ (during fermentation) and 150 kJ (during anaerobic respiration in the muscle cells)

In all organsms: C6H12O6 + 6O2 ----------- 6CO2 + 6H2o z= 2898 kJ

Chemical equation In muscle cellsC6H12)6 ---------------- 2C3H6O3 + 150 kJ

In yeastC6H12O6 ---------------- 2C2H5OH + 2CO2 + 210 kJ

Mitochondria Where the process takes place Cytoplasm1) Glycolysis2) Link Reaction3) Krebs Cycle4) Electron transport

chain and chemiosmosis hypothesis

Stages/process involve Fermentation
