    Figure A

    a. What is the preferred temperature for this enzyme?

    b. What happens to enzyme activity when the temperature exceeds 50oC? What is the technical term used to describe what happens to enzymes when heated to high temperature?

     

    2. Figure B

    Amylase is an enzyme in saliva that digests starch. The graph shows the relationship of pH to amylase activity.

    Figure B

    a. What is the ideal pH for the amylase enzyme?

    b. What the technical term used to describe what happens to the enzyme at very low (acidic) and very high (basic) pH?

     

    3. Figure C

    Relationship of substrate concentration to enzyme reaction rate.

    Figure C

    At what substrate concentration does the enzyme reaction reach half maximal rate?

     

    4. Multiple Choice

    An enzyme reaction is saturated with substrate. How can more product be produced?

    a. add more substrate
    b. add more time
    c. add more enzyme
    d. add more product
