1. Factors affecting enzyme reactions

2. Revision from last lesson
What is a catalyst?
What is the name for biological catalysts?
Where are enzymes found?
Why are enzymes necessary for life?
Name the substrate and product in the following reaction……
starch maltose
amylase

3. Have you finished the tasks from last lesson?
You should have
A paragraph describing the action of amylase
A diagram illustrating lock and key theory
A list of key words and definitions

4. Denaturing High temperatures OR Change from normal pH range
Damage is irreversible
Enzyme will no longer work
Enzyme said to have denatured
At low temperatures enzyme action is very slow as enzyme is fairly inactive (but not denatured)
Change an enzyme’s 3-dimensional structure
