3. Catabolism  is the set of metabolic pathways that breaks down  molecules into smaller units to release energy Definition of Catabolism:

4.  Catabolism breaks down large molecules (such as polysacchrieds,  lipids,nucleic acids and proteins) into smaller units (such as monosacchreids, fatty acids, nucleotides, and amino acids, respectively). EXAPLATION OF CATABOLISM :

5. The purpose of the catabolic reactions is to provide the energy and components needed by anabolic reactions. Microbes simply secrete digestive enzymes into their surroundings, while animals only secrete these enzymes from specialized cells in their guts. Fats are catabolised by hydrolysis to free fatty acids and glycerol. Amino acids are either used to synthesise proteins and other biomolecules, or oxidized to urea and carbon dioxide as a source of energy. Carbohydrates are usually taken into cells once they have been digested into monosaccharides and then processed inside the cell via glycolysis Cont….

6. Protein catabolism  is the breakdown of proteins into amino acids and simple derivative compounds, for transport into the cell through the  plasma membranes  and ultimately for the polymerisation into new proteins via the use of ribonucleic acids (RNA) and ribosomes. Protein catabolism, which is the breakdown of macromolecules, is essentially a digestion process The amino acids produced by catabolism may be directly recycled, used to make new amino acids, or undergo amino acids catabolism to be converted to other compounds via the Krebs cycle.
