A&P Review: Cellular Metabolism

The overall function of metabolism is to:

• Break down nutrients to release energy

• Store energy in the form of fat

• Convert energy into nutrients

• Eliminate waste products from the body

Anabolism and catabolism are two types of metabolic processes. Which of the following statements correctly describes their relationship?

• Anabolism builds up molecules, while catabolism breaks down molecules.

• Anabolism and catabolism both build up molecules.

• Anabolism breaks down molecules, while catabolism builds up molecules.

• Anabolism and catabolism both break down molecules.

Enzymes control metabolic reactions by:

• Increasing the temperature of the reaction

• Lowering the activation energy required

• Changing the pH of the environment

• Providing energy for the reaction

A metabolic pathway is best described as:
