HURRY 80 POINTS!! Enzymes
In this activity, you will follow Demetri, a fellow biology student, as he tests the effects of the lactase enzyme in different conditions and on different solutions.

To begin the experiment, Demetri gathered these materials:

Materials
6 test tubes
safety goggles
3 400-mL beakers
1 microwaveable container
100-mL graduated cylinder
oven mitts
10-mL graduated cylinder
3 tablespoons sugar
a stirrer
75 mL milk
glucose test strips
250 mL water
2 lactase pills
masking tape
a pen
test tube rack

Demetri will use the materials to create the following six solutions:

milk (lactose) in water
milk (lactose) and lactase enzyme in water
milk (lactose) and lactase enzyme in water, heated to boiling
sugar (sucrose) in water
sugar (sucrose) and lactase enzyme in water
sugar (sucrose) and lactase enzyme in water, heated to boiling
Each solution will be made in a test tube. Demetri will insert a glucose test strip into each solution to test for the presence of glucose. The test strip will change color if glucose is present in the solution, as indicated by the following scale.

Part A: Hypothesis and Data Collection
Question 1
Look at these molecular structures. ( Look at images provided below )

Use the molecular structures to predict which of the six solutions will test positive for glucose. Write your prediction in the answer space. Provide the reasoning behind your prediction.
