Question

1. lipase is an enzyme responsible for breaking fat down in the stomach. which statement explains the effectiveness of lipase as it moves through the digestive system from the stomach to the intestine?

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

it becomes less effective because it is used up by fats in the stomach.

it becomes more effective because it changes shape and is able to break down other materials in the intestines.

it becomes more effective because it acquires energy for more reactions from fats.

Explanation:

Enzymes are highly sensitive to pH changes. Lipase functions optimally in a specific pH range. The stomach has a low (acidic) pH, while the small intestine has a more neutral to slightly alkaline pH. As lipase moves from the stomach (acidic environment) to the intestine (a different pH environment), the change in pH inhibits its activity, making it less effective.

Answer:

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