Detailed explanation-1: -Cellular respiration is the process by which food, in the form of sugar (glucose), is transformed into energy within cells.

Detailed explanation-2: -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-3: -During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water. Along the way, some ATP is produced directly in the reactions that transform glucose. Much more ATP, however, is produced later in a process called oxidative phosphorylation.

Detailed explanation-4: -If cellular respiration takes place in the presence of oxygen, it is known as aerobic respiration. If it takes place in the absence of oxygen, it is known as anaerobic respiration. Enzyme-catalyzed reactions are responsible for breaking down organic molecules (usually carbohydrates or fats).

Detailed explanation-5: -In cellular respiration, glucose and oxygen react to form ATP. Water and carbon dioxide are released as byproducts.
