Question

3 you will be measuring glucose levels. why is that a good way to determine lactase activity? 4. predict what will happen to glucose levels if lactase is more active/efficient versus less active/efficient. if its more active, then glucose levels will go up.

Explanation:

Lactase breaks lactose into glucose and galactose. Measuring glucose levels can indicate lactase activity as more active lactase will produce more glucose. If lactase is more active, it will break down more lactose into glucose, increasing glucose levels; if less active, less lactose is broken down, resulting in lower glucose levels.

Answer:

1. Lactase breaks lactose into glucose and galactose. Higher glucose levels indicate more lactase - catalyzed reactions, thus measuring glucose levels can reflect lactase activity.
2. If lactase is more active/efficient, glucose levels will increase; if less active/efficient, glucose levels will be lower.
