Reactions involving Enzymes

Enzymes are biological catalysts.

They are natural proteins. An enzyme works because it is the right shape to hold the reactant particles together.

If an enzyme gets too hot this shape is destroyed. We say they have been denatured. They no longer work as a catalyst.

Enzymes are used to brew beer, make cheese and in biological washing powders.
