Answer:
Living organisms use energy released by respiration for their life functions. There are two types of respiration - aerobic respiration and anaerobic respiration. Two of these processes are different due to following reasons:
1. Requirement of oxygen: Aerobic respiration requires oxygen to breakdown glucose. Anaerobic respiration does not requires oxygen to breakdown glucose.
2. Breakdown of glucose: In aerobic respiration glucose is broken down completely into byproducts whereas, in anaerobic respiration glucose is not broken down completely.
3. End products: In aerobic respiration the byproducts are carbon dioxide and water whereas in anaerobic respiration in animals : lactic acids and in plants and yeast: carbon dioxide and ethanol.
4. Amount of energy production: In aerobic respiration, the energy released is in large amount due to complete breakdown of glucose whereas, in anaerobic respiration the energy is less due to incomplete glucose breakdown. Aerobic respiration produces 36-38 ATP molecules whereas, anaerobic respiration produces 2-36 ATP molecules.
5. Reaction site: In aerobic respiration, the reaction site is mitochondria or cytoplasm and in anaerobic respiration, the reaction site is only cytoplasm.
