factor effecting on respiration
Answers
1. The process of respiration is influenced by a number of external and internal factors.
2.The main external factors are temperature, light, oxygen supply, water supply, CO2 concentration, toxic and stimulating substances and disease and injury.
(a) External Factors:
1.Temperature: Below 20¡C and above 45¡C the rate of respirationreduces. The optimum temperature for respiration is 20¡C - 45¡C.
1.Temperature: Below 20¡C and above 45¡C the rate of respirationreduces. The optimum temperature for respiration is 20¡C - 45¡C.2.Oxygen: If the amount of oxygen is reduced the rate of respiration willreduce.

The optimum temperature for respiration is 20¡C - 45¡C.2.Oxygen: If the amount of oxygen is reduced the rate of respiration willreduce.3.Water: Optimum supply of water maintains the rate of respiration normal.Rate of respiration reduces for scarcity of water.

(b) Internal Factors: 1.Food materials: During respiration food materials break to release water andCO2. So the quality and quantity of food materials in the cell regulates the rate of respiration.

3. Enzymes: Different reactions of respiration need different kinds of enzymes.The process completely depends on their presence.
