Proteins and Enzymes

HideShow resource information

Biological catalysts- increase the rate of chemical reactions however they do not get used up.

The place where the substrates fix in to each other this is called the active site.

Two small molecules before making a substrate forms a larger molecule.

The shape of the active site can change and this is calle denatured this will then mean that the enzyme will not work anymore.Enzymes are made of living things however they are proteins and are not alive. 

Enzymes become denatured at high temperatures or incredible PH. 

DONT SAY THE ENZYME HAS BEEN KILLED!

If temperture is higher then the rate of reaction increases.This then happens to denature the enzyme, because it would have reached its optimum temperture.Thirty seven degrees is the optimum rate for an enzyme
