Front

Define carbohydrates.

Back

Organic compounds made of carbon, hydrogen, and oxygen, primarily used for energy.

Front

What are lipids and their primary function?

Back

Lipids are hydrophobic molecules that store energy and make up cell membranes.

Front

What is the role of proteins in living organisms?

Back

Proteins serve as enzymes, structural components, and play roles in cell signaling.

Front

What are nucleic acids and their function?
