ummm, what's catobolism?

Large polymeric molecules such as polysaccharides, nucleic acids, and proteins are first split into their constituent monomeric units, such as amino acids, after which the monomers themselves can be broken down into such simple cellular metabolites as lactic acid, acetic acid, carbon dioxide, ammonia, and urea. The first set of reactions provides the cell with monomers with which it can construct new polymeric molecules. The second set of reactions usually involves the process of oxidation and is accompanied by a release of chemical free energy, not all of which is lost as heat, but is partially conserved through the coupled synthesis of adenosine triphosphate. The hydrolysis of this compound is subsequently used to drive almost every energy-requiring reaction in the cell. Thus catabolism also provides the source of chemical energy necessary for the maintenance of the living cell. or: Catabolism From Wikipedia, the free encyclopedia. Catabolism is a process in which a cell breaks down complex molecules to produce energy and reducing power, it is therefore normally exothermic. It is half of the coupled process of metabolism, the other part being anabolism. Carbohydrate catabolism Carbohydrate catabolism is the breakdown of carbohydrates into smaller units. The empirical formula for carbohydrates, like that of their monomer counterparts, is CX(H2YOY). Carbohydrates literally undergo combustion to retrieve the large amounts of energy in their bonds. Read more about mitochondria to find out more about the reaction and how its energy is secured in ATP. Fat catabolism Fat catabolism, also known as lipid catabolism, is the process of lipids or phospholips being broken down by lipases. The opposite of this is fat anabolism which involves the storage of energy, and the building of cell walls. Protein catabolism Protein catabolism is the breakdown of proteins into amino acids and simple derivative compounds, for transport into the cell through the plasma membrane and ultimately for the polymerisation into new proteins via the use of ribonucleic acids (RNA) and ribosomes. -------------- Veda MISERY IS OPTIONAL ***When you are up to your ears in trouble, try using the part that is not submerged. ***The difference between a dream and a goal is a plan.

Whatcha been up to, Woodie?! How have you been!? -------------- Veda MISERY IS OPTIONAL ***When you are up to your ears in trouble, try using the part that is not submerged. ***The difference between a dream and a goal is a plan.

You want to try and prevent catabolism by eating a protein and nutrient rich diet that will promote muscle repair and rebuilding (anabolism). -------------- \"Achieving worthwhile goals requires a consistent investment of time and effort on your part....The rewards you receive will be in direct proportion to the consistent effort you put forth.\" Brian Johnston, The Power of The Champions
