How the concentration of amylase effects the digestion of the starch.

Aim: To investigate whether changing the concentration of enzymes makes a difference to the rate of reaction.

Planning:

Enzymes are biological catalysts. They speed up the chemical reactions, which go on inside living things. Enzymes provoke all the process necessary for life. Minerals, vitamins and hormones need enzymes to be present in order to do their work properly.They are very efficient at their job. Enzymes are made inside cells. Once formed, the enzyme may leave the cell and work outside.

Substrate Product

-------------------------------------

The substance which the enzyme acts on is called the SUBSTRATE .The new substances formed as a result of the reaction are the PRODUC. For convenience enzymes are usually given a name similar to that of the substrate but with the ending 'ase'.

PRELIMINARY WORK- Before starting my actual experiment for my investigation, I had prepared some preliminary. In this experiment I tried out, with different concentrations of amylase with starch to see how long it would take for the starch to convert into glucose. In order to determine the
