Front

What are lipids?

Back

Lipids are a group of macromolecules that include fats, oils, and butter, which are high in energy.

Front

What role do enzymes play in biochemical reactions?

Back

Enzymes act as catalysts that lower the activation energy needed for reactions to occur.

Front

What is the primary function of carbohydrates?

Back

Carbohydrates primarily serve as a source of energy for the body.

Front

What are proteins made of?
