2. Answer true of false to the following statements:

a. _______ Enzymes interact with specific substrates
b. _______ Enzymes change shape after a reaction occurs
c. _______ Enzymes speed up reactions.
d. _______ One enzyme can be used for many different types of chemical reactions.
e. _______ Enzyme reactions can be slowed or halted using inhibitors.

3. Circle the correct effect.

a. Raising the temperature slightly will [ increase | decrease | not change ] the rate of reaction
b. Boiling temperature will [ increase | decrease | not change ] the rate of reaction.
c. Changing the pH toward the optimal pH will [ increase | decrease | not change ] the rate of reaction.
d. Introducing a competitive inhibitor will [ increase | decrease | not change ] the rate of reaction.

4. Place a check mark next to the things that are expected to INCREASE the rate of an enzymatic reaction

a. _______ Add more enzyme
b. _______ Add more substrate
c. _______ Adjust pH to optimal level
d_______ Add a non competitive inhibitor
e._______ Freezing
