3. During an investigation of a freshwater lake, an AP Biology student discovers a previously unknown microscopic organism. Further study shows that the unicellular organism is eukaryotic.
(a) Identify FOUR organelles that should be present in the eukaryotic organism and describe the function of each organelle.
(b) Prokaryotic cells lack membrane-bound organelles found in eukaryotes. However, prokaryotes must perform many of the same functions as eukaryotes. For THREE of the organelles identified in part (a), explain how prokaryotic cells carry out the associated functions.

Essay Questions for your wonderment...
1. Discuss the lock-and-key theory of enzyme-substrate interaction giving a
specific example to illustrate the theory. Include in your discussion the effects of each of the following:
a. Substrate concentration
b. pH shifts
c. Temperature shifts
d. Competitive inhibition
2. After an enzyme is mixed with its substrate, the amount of product formed is determined at 10-second intervals for 1 minute. Data from this experiment are shown below.
Time (sec) 0 10 20 30 40 50 60
Product formed (mg) 0.00 0.25 0.50 0.70 0.80 0.85 0.85
Draw a graph of these data and answer the following questions.
a. What is the initial rate of this enzymatic reaction?
b. What is the rate after 50 seconds? Why is it different from the initial rate?
c. What would be the effect on product formation if the enzyme were heated to a temperature of 100 oC for 10 minutes before repeating the experiment? Why?
d. How might altering the substrate concentration affect the rate of the reaction? Why?
e. How might altering the pH affect the rate of reaction? Why?
3. Enzymes are biological catalysts.
a. Relate the chemical structure of an enzyme to its specificity and catalytic activity.
b. Design a quantitative experiment to investigate the influence of pH or temperature on the activity of an enzyme.
c. Describe what information concerning the structure of an enzyme could be inferred from your experiment.
