Question

an animal's stomach contains enzymes that break down food into smaller molecules that the animal's cells can use enzymes perform this function by a. participating in chemical reactions b. increasing the reaction temperature c. decreasing the activation energy d. lowering the pH

Answer 1

A, because the temperature and pH in the stomach are already suitable for the enzymes' actions.

Answer 2

Answer: Option C

Explanation:

An animal's stomach contains enzymes that breaks the food into more simpler form. The enzymes in the stomach acts as the catalyst which decreases the activation energy.

The enzymes just increases the rate of reaction and do not take part in product formation and this is the reason enzymes are found in the stomach.

The decreased activation energy will provide more energy for the other process.
