Biomolecules and Their Functions

Biomolecules are produced by living organisms and are vital to life. Which biomolecule is matched correctly to a function that it performs?

• Nucleic Acids: Act as enzymes to speed up chemical reactions

• Lipids: Form the main fabric of plasma membranes

• Carbohydrates: Store excess sugar for long-term energy

• Proteins: Carry genetic information into the cytoplasm

In order to prepare for the winter months, bears will consume extreme amounts of food to preserve the fat needed for hibernation. Which of the following explains the importance of fat storage for bears?

• Fat is a source of stored energy for body cells to use during hibernation.

• Fat is a building block for extra vitamins and the immune system during hibernation.

• Fat provides nutrients to grow thicker fur to keep warm during hibernation.
