Bell Work- What ending do all enzymes have? -ase
Enzymes-the substance (reactant) an enzyme acts on is the substrate.
Active Site- A restricted region of an enzyme molecule that binds to the substrate.
The substrate fits into the enzyme.
What are 3 tings that affect an enzymes ability to do its work? What affects enzyme activity?
Three factors:
1. Environmental Conditions
2. Cofactors and Coenzymes
3. Enzyme Inhibitors
We need enzymes to help speed up chemical reactions.
Enzymes can perform 2 actions.
(Students should have drawing in their notes to help them understand.)
