Question

How does aerobic respiration differ from anaerobic respiration? Mention two practical applications of alcoholic fermentation.

Accepted Answer

Features Aerobic respiration Anaerobic respiration

Definition It is a metabolic process in which glucose is oxidized into pyruvic acid in the presence of oxygen and energy is released. It is a process in which glucose is oxidized into ethyl alcohol (in plants) and lactic acid (in animals).

Features Aerobic respiration Anaerobic respiration

Site of occurrence It takes place in mitochondria and cytoplasm. It takes place in the cytoplasm only.

Features Aerobic respiration Anaerobic respiration

End product Carbon dioxide and water are the end products with the release of 36 molecules of ATP Carbon dioxide and ethyl alcohol (in plants) lactic acid (in animals) are the end products with the release of 2 molecules of ATP.

Two application of Alcoholic fermentation are as follow:

1. Alcohol is useful in the wine industry, preparation of different medicine, tonics, biochemical and medicinal research, biological experiments, cosmetics, etc.

2. The carbon dioxide generated during fermentation is also an important component of many baked goods like cake, bread, cookies, pastries, muffins etc.
