What describes a solution with a higher solute concentration than the cell?

Hypertonic

What describes a solution with a lower solute concentration than the cell?

Hypotonic

What describes a solution with the same solute concentration as the cell?

Isotonic

What is a monomer?

A single molecule that can link together with other monomers to form polymers.

What is a polymer?

A long chain of several monomers linked together.

What are carbohydrates primarily used for?

Energy release and storage.

What is the monomer of carbohydrates?

Glucose

What are lipids primarily used for?

Energy storage in the body and make up cell plasma membranes.

What is the monomer of lipids?

Fatty Acid

What are proteins used for?

Diverse functions including digestion, contraction, transport, defense, structural support, and serve as hormones.

What is the monomer of proteins?

Amino Acid

What is the purpose of nucleic acids?

Storing and transmitting genetic information in DNA and RNA.
