Document Summary

Metabolism: entire network of enzyme reactions in cells. Anabolism: reactions that synthesize molecules or make more complex molecules. Catabolism: reactions that degrade larger molecules to smaller molecules. Anabolism: reactions require energy and produce a wide diversity of macromolecules using a smaller number of simpler molecules. e. g 20 amino acids used to make thousands of proteins. Catabolism: these reactions usually liberate energy and can convert a wide variety of larger molecules into a smaller variety of small molecules e. g. thousands of proteins . Glycolysis: breakdown of glucose 6c to 2 pyruvate 3c. Oxidation: breakdown of fatty acids to acetyl coa. Generally energy released during catabolism is used in anabolic pathways or in cellular work (e. g. muscle contraction) Pathways: the synthesis or breakdown of a molecule usually relies on a number of sequential enzyme reactions. The product of one reaction serves as substrate for the next enzyme in line.
