Digestive System Lab Assessment

You and your partner are lab technicians at a nutrition center. Your supervisor wants to see what you know about enzymes, digestion, and chemical testing.

She gives you two containers of starch solution, one labeled "A" and one labeled "B." She informs you that one bottle contains a digestive enzyme that is found in the mouth; the other bottle does not contain an enzyme.

Using the equipment and materials supplied, determine which solution, A or B, contains the digestive enzyme. Record the procedures you use to analyze the substance. Record your results and give evidence to support your conclusions. Use the questions that follow.
