Question

lipase is an enzyme responsible for breaking fat down in the stomach. which statement explains the effective of lipase as it moves through the digestive tract? a it becomes less effective because it is used up by fats in the stomach. b it becomes more effective because it acquires energy for more reactions from fats. c it becomes less effective because it is inhibited by the change in ph from the stomach to the intestines. d it becomes more effective because it changes shape and is able to break down other materials in the intestines.

Explanation:

Enzymes are pH - sensitive. A change in pH can affect the enzyme's structure and function. Lipase works optimally in a certain pH range. As it moves from the stomach to the intestines, the pH changes, inhibiting its activity.

Answer:

B. It becomes less effective because it is inhibited by the change in pH from the stomach to the intestines
