What is the importance of enzymes in the body?
Where are enzymes synthesized?
What is their molecular structure and chemical make up?
Where are enzymes manufactured?
What is the function of enzymes in cells?
How do enzymes lower the activation energy of a reaction?
Give five specific examples of enzymes.
Identify four characteristics of enzymes.
What affect do the following conditions have on enzymes?
a) pH
c) competitive inhibitors
b) temperature
d) non-competitive
inhibitors
10.What are the optimum temperatures and pH for enzymes to work in our bodies?
11.Name the factors that affect the production of an enzyme?
12.What are the 3 ways that an apoenzme (the protein portion) is denatured?
13.Know how to interpret graphs in this section. Why isn’t the temperature graph
symmetrical?
14.Explain the lock and key analogy.
15.Another more recent explanation of enzyme action is the "induced fit" theory.
Describe the basics of this theory.
16.What is an active site, and how can it be changed?
17.Describe how different concentrations and competitive inhibitors can affect
enzymes.
18.What is the role of thyroxin in the body? Where is it made?
19. Differentiate between the following:
a) potential and kinetic energy
b) ADP and ATP
c) degradative reaction (catabolic) and synthetic reactions (anabolic)
