1. SB1b. Explain how enzymes function as catalysts.

2. ENZYME FOLDABLE 2 3 1 4

3. Tab 1: Enzyme, Substrate and Active site
Enzyme – protein that catalyzes chemical reactions for organisms.
Substrate – reactant in a chemical reaction upon which an enzyme acts.
Active site – where the enzyme binds.
Catalyze- speed up a reaction

4. Tab 2 – Induced Fit
Induced Fit - An enzyme-substrate complex forms when the enzyme’s active site binds with the substrate like a key fitting a lock. 
The shape of the enzyme must match the shape of the substrate. Enzymes are therefore very specific; they will only function correctly if the shape of the substrate matches the active site.

5. Tab 3: Factors that Affect Enzymes
Temperature pH
Concentration
Inhibitors

6. Tab 4: Examples of biological enzymes
Pepsin
Lipase
Amylase
Ligase
Helicase
Many, many more

7. Center Fold Enzyme are NOT used up and are reuseable.
Enzymes are VERY specific they will ONLY work with the right substrate.
Enzyme break chemical bonds.
Enzymes lower activation energy- or energy needed to start a reaction.
