Without enzymes the reactions that take place in an organism would be too slow for life to continue. Enzymes are proteins and how an enzyme functions is determined by its three dimensional structure. An enzyme has:> Three dimensional shape> Area on its surface called Active site The substance that the enzyme helps to react is called the substrate. Substrate has complementary to the active site and the substrate fits into the active site. The active site of each of each different enzyme has its own particular three-dimensional shape so only a substrate with a complementary shape will fit it.
