Document Summary
Metabolism: entire network of enzyme reactions in cells. Two major domains: organized in pathways to do things for you, anabolism: reactions that synthesize molecules or make more, catabolism: reactions that degrade larger molecules to smaller complex molecules. 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. Making chemical bonds: requires energy, divergence thousands of possibilities. From simple number of building blocks to huge number of complex molecules put together. Have to maintain blood sugar to get through the night: synthesis of glucose from pyruvate, synthesis of glycogen (polyglucose) from glucose, synthesis of fatty acids from acetyl coa. These liberate energy and can convert a wide variety of larger molecules into a smaller variety of small molecules reactions usually: e. g. thousands of proteins 20 amino acids, converging, changing to simpler molecules smaller numbers.
