CHAPTER 8
ENZYMES AND METABOLISM
1. How are “chemical reactions” important to an organism?
Below is a “chemical equation”.
2. If the product is carbonic acid, what are the reactants in
this equation?
3. What does the double arrow indicate?
4. What is the biological importance of this equation?
Below is the chemical equation for the combustion of hydrogen gas.
5. What does the term “coefficient” mean in reference to a
molecule?
6. Is this an “exergonic” or “endergonic” reaction?
Below is a diagram representing a chemical reaction using a rock as an example. “A” would be the
reactants and “B” would be the products.
7. Label “activation energy” on the diagram.
8. Would this be an “exergonic” or “endergonic” reaction?
Below are two sets of graphs representing chemical reactions aided by “enzymes”.
10. What macromolecule group do
most enzymes belong to?
9. How do enzymes aid chemical
reactions?
10. What is the name of the enzyme that would be
involved in this reaction?
11. What does the enzyme’s name end with
(suffix)?
12. What process would the enzyme “lactase” aid
in?
Below is a diagram representing an “enzyme-substrate complex”.
13. What is the name of the substrate
in this reaction?
14. What is the name of the enzyme?
15. Label the active site of the enzyme.
16. What is the solvent that converts
the substrate to the products?
17. What are the products of this
reaction?
Below is a graph representing the “regulation” of enzymatic activity.
18. What is the independent and dependent variables in
this graph?
19. What is the factor regulating these two enzymes?
20. Which enzyme would you find in the human stomach?
Why?
