EVERYDAY SCIENCE

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: -Anabolism creates molecules the body needs for functionality and it uses energy in the process. Catabolism, on the other hand, breaks down complex molecules and releases energy which is available for the body to use.

Detailed explanation-5: -Two types of metabolic reactions take place in the cell: ‘building up’ (anabolism) and ‘breaking down’ (catabolism). Catabolic reactions give out energy.
