Question

Explain the difference in the two curves. Why did glucose concentrations increase over time

in the presence of 5 mM lactase, but did not increase over time in the absence of lactase?
What can you conclude about the ability of lactose to "spontaneously" break apart into
glucose and galactose? (2-4 sentences)

Answer 1

The shape of sucrose (glucose and fructose) is different from lactose (glucose and galactose).

Step-by-step explanation:

The sucrose will not fit into the active site of lactase. The concentration of galactose will increase, and the concentration of lactose will remain the same.
