3. What is the responsibility of the gallbladder? How<br />
do you think having the gallbladder removed will<br />
affect digestion?<br />
4. What is an enzyme?<br />
5. Explain the function and location of the following<br />
enzymes: amylase, pepsin, trypsin, and lipase.<br />
6. Diagram A shows the rate of enzyme activity of<br />
digestive enzymes – amylase, pepsin, and trypsin –<br />
in a variety of pH. Using the knowledge of what you<br />
learned during this lab, identify which enzyme is most<br />
like A, B, and C in the graph. Explain your answer.<br />
