METABOLISM

Which of the following best defines catabolism?

• The breakdown of molecules to release energy

• The breakdown of molecules to obtain energy

• The breakdown of molecules to obtain nutrients

• The process of breaking down waste products

Anabolism is:

• The breakdown of molecules to obtain energy

• The storage of energy in the body

• The synthesis of compounds needed by the cells

• The process of converting nutrients into energy

What term describes the biochemical or metabolic pathways by which the cell ultimately obtains energy?

• Bioenergetics

• Anabolism

• Catalysis

• Nutrition

What role do essential nutrients play in metabolism?

• They provide energy and necessary chemicals the body cannot synthesize

• They store excess energy

• They regulate metabolic pathways

• They promote muscle growth

What do enzymes do in metabolism?

• Synthesize complex molecules from simple ones

• Regulate metabolic pathways and speed up reactions

• Transport nutrients across cell membranes

• Convert light energy into chemical energy
