2. What is effect of temperature of enzyme activity?
- enzyme works best at very high temps
- increases it to a point(optimum temp) where it then denatures
- enzyme works best at very low temps
- increases it indefinitely
3. What is the effect of competitive inhibitors on enzymes?
- binds to the active site temporarily and lowers reaction rate
- binds to the active site permanently
- speeds up the reaction
- no effect
4. What is the effect of non-competitive inhibitors on enzymes?
- binds to the enzyme permanently, irreversible
- binds to the enzyme temporarily, reversible
- speeds up the reaction
- no effect
5. What is the active site?
- something all proteins have
- region on the enzyme the substrate binds to
- region on the substrate the enzyme binds to
- a shape on the enzyme that fits a range of substrates
