Cellular Respiration Process By Which Plants. Both animals and plants resort to this process wherein they use nutrients such as glucose amino acids and fatty acids to produce energy. Although carbohydrates fats and proteins are consumed as reactants aerobic respiration is the preferred method of pyruvate breakdown in glycolysis and requires pyruvate to the mitochondria in order to be fully oxidized by the citric acid cycle.
The chief respiratory substrate is glucose. Generally all protoplasmic substances which release energy after oxidation are termed respiratory substances but precisely respiratory substrate are those which on oxidation break down to carbon dioxide and water. The common oxidizing agent in this process is molecular oxygen.
Respiration in plants can define as a cellular mechanism which involves complete combustion of glucose and oxygen to yield by products like water and carbon dioxide and energy in the form of heat.
Aquatic plants undergo photosynthesis and cellular respiration much like terrestrial plants. Generally all protoplasmic substances which release energy after oxidation are termed respiratory substances but precisely respiratory substrate are those which on oxidation break down to carbon dioxide and water. Although carbohydrates fats and proteins are consumed as reactants aerobic respiration is the preferred method of pyruvate breakdown in glycolysis and requires pyruvate to the mitochondria in order to be fully oxidized by the citric acid cycle. In this process nutrients obtained from the soil are converted into energy and are used for different cellular activities.
