Detailed explanation-1: -Catabolism (pronounced: kuh-TAB-uh-liz-um), or destructive metabolism, is the process that produces the energy needed for all activity in the cells. Cells break down large molecules (mostly carbs and fats) to release energy.

Detailed explanation-2: -Catabolism is what happens when you digest food and the molecules break down in the body for use as energy. Large, complex molecules in the body are broken down into smaller, simple ones. An example of catabolism is glycolysis. This process is almost the reverse of gluconeogenesis.

Detailed explanation-3: -Respiration is a catabolic process as it breaks down complex molecules into simpler ones with release of energy in the form of ATP molecule.

Detailed explanation-4: -Catabolism – the breakdown of food components (such as carbohydrates, proteins and dietary fats) into their simpler forms, which can then be used to provide energy and the basic building blocks needed for growth and repair.

Detailed explanation-5: -Catabolic and Anabolic Reactions The breakdown of food in digestion is a catabolic reaction (see digestive system). Foods are generally in the form of proteins, carbohydrates, and lipids (also called fats).
