<strong>Lab</strong> 9: Enzymes<br />
5. There is another digesve enzyme other than salivary amylase that is secreted by the salivary<br />
glands. What is this enzyme? What substrate does it act on? Where in the body does<br />
it become acvated, and why?<br />
6. Saliva does not contain amylase unl babies are about two months old. How could this<br />
affect an infant’s digeson? (Hint: babies do not eat cereal unl about three months old)<br />
7. Many common household products contain enzymes (e.g., meat tenderizer, enzyme detergent).<br />
Can you think of any other household uses for enzymes?<br />
