Which of the following statements identifies how catabolism and anabolism relate to metabolism?

• Catabolism and anabolism are two distinct processes that are not involved in metabolism.

• Metabolism relies on anabolic reactions to provide energy to fuel catabolic reactions.

• Catabolism and anabolism are interdependent processes that together make up metabolism.

• Metabolism involves catabolic reactions to break down nutrients, while anabolic reactions synthesize new structures.

Which of the following identifies the effect of enzymes on metabolism?

• Each macromolecule utilizes specific enzymes that speed up metabolic reactions.

• Metabolic reactions take place without the need to utilize enzymes.

• Enzymes inhibit metabolic reactions from taking place within the body.

• 
  The same enzyme can be used in chemical reactions to break down each macromolecule.

Which of the following statements identifies the effect hormones have on metabolism?

• Hormones regulate the breakdown or synthesis of macromolecules.

• Hormones do not play a role in metabolic reactions.

• Hormones can stimulate or inhibit metabolic reactions.

• Hormones accelerate the breakdown or synthesis of macromolecules.
