Question

Clarify the difference between the two types of Respiration?

Answer 1

Aerobic respiration	Anaerobic respiration
1. Oxygen is needed in aerobic respiration	1. Oxygen is not needed in anaerobic respiration.
2. Here, complete oxidation of glucose takes place.	2. In anaerobic respiration, the glucose molecule is incompletely broken down.
3. End products of aerobic respiration are; CO2, water and energy; C6H12O2 + 6O2→ 6H2O + 6 CO2 + 686 kcal energy	3. End products of anaerobic respiration are ethyl alcohol, carbon dioxide. 50 kcals energy is given off. C6H12O2 → 2C2H5OH + 2CO2 + 50 kcal Energy.
4. 38 ATP molecules are formed.	4. Only two molecules of ATP are formed.
5. Respiratory material is completely oxidised.	5. Respiratory material is not completely oxidised.
6. It is a normal method of respiration and occurs in all living cells.	6. It is present only in few organisms sand in others, it occurs for short duration in like fungi, bacteria, etc.
