ANSWER

The difference between aerobic and anaerobic respiration.

Aerobic respiration Anaerobic respiration

1. Aerobic respiration refers to complete breakdown of metabolic fuels in presence of oxygen. 1. Anaerobic respiration is the process of partial breakdown of fuel (glucose) in absence of oxygen.

2. It includes glycolysis, citric acid cycle and oxidative phosphorylation. The first two processes take place in the cytoplasm while last one occurs in mitochondria. 2. Glycolysis is followed by ethanol fermentation (occurs in yeast) or lactic acid fermentation (in muscles and microbes like lactic acid bacteria).

3. The end products are carbon dioxide and water. 3. End products of ethanol fermentation are ethanol and carbon dioxide; that of lactic acid fermentation are lactic acid

4. Owing to complete oxidation of glucose, a large amount of energy is produced (36-38 ATP molecules) 4. Incomplete oxidation of glucose does not release all stored energy and only 2 ATP molecules are produced.

Anaerobic respiration is carried out by yeast and other anaerobic organisms like lactic acid bacteria, E. coli, Staphylococcus, Clostridium etc.

Answer 2

Explanation:

Anaerobic respiration occurs when oxygen is not present. It consists of two steps. The first step, like aerobic respiration, is glycolysis, that produces ATP from the reactant glucose.

Aerobic respiration can only occur in the presence of oxygen. During aerobic respiration, the reactants oxygen and glucose are turned into the products carbon dioxide, water, and ATP.
