Detailed explanation-1: -Catabolism is defined as all chemical or enzymatic reactions involved in the breakdown of organic or inorganic materials such as proteins, sugars, fatty acids, etc. From: Bacterial Cellular Metabolic Systems, 2013.

Detailed explanation-2: -Catabolic pathways are those that generate energy by breaking down larger molecules. Both types of pathways are required for maintaining the cell’s energy balance. It is important to know that the chemical reactions of metabolic pathways don’t take place spontaneously.

Detailed explanation-3: -Some examples of the catabolic processes include glycolysis, the citric acid cycle, the breakdown of muscle protein in order to use the amino acids as substrates for gluconeogenesis, the breakdown of fat in adipose tissue to fatty acids, and oxidative deamination of neurotransmitters by monoamine oxidase.

Detailed explanation-4: -Anabolism requires energy to grow and build. Catabolism uses energy to break down. These metabolic processes work together in all living organisms to do things like produce energy and repair cells.
