Features affecting rate of respiration are given below:Temperature: Optimum temperature for respiration is between 20-35 degree celsius. Maximum temperature is about 45 degree celsius.At low temperature respiration is low due to inactivation of enzymes while at very high temperature as enzymes denatured.Oxygen:The inhibition of anaerobic respiration by oxygen concentration is called Pasteur’s effect.The amount of oxygen at which aerobic and anaerobic respiration take place simultaneously is called transition point.The minimum amount of oxygen at which aerobic and anaerobic respiration become extinct is called extinction point.Carbon Dioxide:Carbon dioxide increases then the rate of respiration decreases in plants.Preservation of fruits and vegetables at high concentration is called gas storage.Salts:If a plant is transferred from water to salt solution, it’s respiration increases this is known as salt respiration.
