1. Explain why a glucose test strip may be used to determine the enzymatic activity of lactase.
Homework Answers
Answer: Glucose test strips may be used to determine the enzymatic activity of lactase because lactase is an enzyme for digestion which breaks down lactose into glucose and galactose., which are easily digested by humans.Thus, Glucose test strips can be used to determine if there is any enzymatic activity of lactose or not.

Use your answer to question 2 to explain why testing for glucose concentration is a good indication of lactase activity on all of those substrates. 4 Convert 37°C to the corresponding value in Fahrenheit. Why do you think most of the experiments in this lab are conducted at 37°C?

The mucic acid test may be used to differentiate glucose and galactose. The test involves reaction with nitric acid, which oxidizes both aldehyde and primary alcohol groups. Explain how this test differentiates glucose from galactose. What other laboratory procedure must be performed to accomplish the differentiation?

Problem 5, (25pts) To assess the quality of medical strips, used to test the level of glucose in the blood, one must control the consistency, that is resulted from the same sample if many repeated measures are obtained from that sample. If the variance in the results is too high the strip is considered as inconsistent and lower quality. Two possible strips are tested and compared with each other strip A and strip B and the results were recorded as...
