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

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: -Cellular respiration takes place in the cells of animals, plants, and fungi, and also in algae and other protists. It is often called aerobic respiration because the process requires oxygen (the root aer comes from the Greek word for “air”).
