Biology SC1 'How dose concentration affect the rate of a chemical reaction.' * Introduction An enzyme is a protein molecule that speeds up chemical reactions in all living things. All living cells make enzymes but enzymes are not alive. Enzyme molecules function by altering other molecules. Enzymes combine with altered molecules to form a complex molcule structure in which chemical reactions take place. Enzymes are specific, they only control one type of reaction although they are specific, all enzymes work in a very similar way and have similar properties. They are all globular proteins and are all biological catalysts, they increase the rate of a given reaction without being used up and their presence does not change the nature of the reaction or the end product. Enzymes work by having an actire site, made from amino acids. Here substrate molecules will bind with enzyme (and other substrate molecules if nesscesary) and a reaction takes...
