: Cellula respiration
Answers
Explanation:
Cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.
Respiration is the process which involves the chemical break down of glucose to release ATP (energy) for the body. C02 is a biproduct which is expelled through the lungs.
There are two types of respiration: -
Aerobic respiration - This is the breakdown of Glucose in the abundance of oxygen this is the more efficent of the two processes and creates the most amount of energy. 52 molecules of ATP.
CHEMICAL FORMULA for Aerobic respiration : -
Anaerobic respiration - This is the breakdown of Glucose in the absence of oxygen. This is not an efficient process, only 2 molecues of ATP are produced and a biproduct is lactic acid. which is what causes aches and cramps in muscles after excercise.
