A change in temperature affects an enzyme by causing the enzyme to change it's shape.
<h3>what is an enzyme?</h3>
An enzyme is a substance that catalyzes chemical reactions. 
- Temperature is one of the major factors that aid enzymes action.
- Increase in temperature could increase the rate of enzyme.
- However, at a very high temperatures, the enzyme can be denatured thereby changing it shape or structure and the enzyme may no longer bind to the substrate or function effectively this will then reduce the rate of chemical reaction. 
 Therefore, a change in temperature i.e very high temperature can change the shape of an enzyme.
