INTRODUCTION. Enzymes are a biological catalyst, which speed up or slow down many chemical reactions. However, the enzyme itself will remain unchanged. Various temperatures can affect the rate of reaction. Enzymes are proteins constructed from chains of amino acid and are present in all living things. Living cells produce enzymes. They are specific in their action, they are a 3-dimensional molecule and work within a certain range of temperature; all enzymes have their own optimum temperature. The shape of the active site fits only one type of molecule so each enzyme controls a particular type of chemical reaction. Substrate binds to the active site to form on the enzyme substrate complex where the reaction takes place and the product is released leaving the enzyme free to work again. Sucrase is an enzyme and has an optimum (the temperature that promotes maximum activity) temperature of 37 0 c, and catalyses...
