Biology - Investigating the effect of Enzyme Concentration Aim To investigate the effect of enzyme concentration on the rate of reaction the enzyme controls, using amylase and starch to illustrate this. Introduction An Enzyme is a protein, which is capable of starting a chemical reaction, which involves the formation and/or breakage of chemical bonds. The Features of Enzymes are: - Speeds up the Rate of Reaction - Is a biological catalyst - Denatures if the temperature is too high - Lower activation energy Enzymes are very particular - they won't catalyze just any old reaction, only those which are suited for the enzyme. This selectivity is because of the essentially fixed shape of the place where the molecules must get together within the enzyme's reaction site in order to get close enough to form a bond. Bacteria too, must have function enzymes available. Being only a single cell with only a single chromosome, bacteria is quite astonishing in their ability...
