DENDROLOGY

Detailed explanation-1: -Cellular respiration is the process that occurs in the mitochondria of organisms (animals and plants) to break down sugar in the presence of oxygen to release energy in the form of ATP. This process releases carbon dioxide and water as waste products.

Detailed explanation-2: -Cellular respiration is the process of extracting energy in the form of ATP from the glucose in the food you eat. Oxygen and glucose are both reactants of cellular respiration. When one molecule of glucose is broken down, it can be converted to a net total of 36 or 38 molecules of ATP.

Detailed explanation-3: -The most important process in stage 2 of the breakdown of food molecules is the degradation of glucose in the sequence of reactions known as glycolysis-from the Greek glukus, “sweet, ‘’ and lusis, “rupture.” Glycolysis produces ATP without the involvement of molecular oxygen (O2 gas).

Detailed explanation-4: -The first stage of cellular respiration, called glycolysis, takes place in the cytoplasm. In this step, enzymes split a molecule of glucose into two molecules of pyruvate, which releases energy that is transferred to ATP.
