What is the function of nucleic acids?

• To provide structural support to cells.

• To store and transmit genetic information.

• To catalyze biochemical reactions.

• To transport nutrients across cell membranes.

Why do fats release more energy than carbohydrates?

• Because fat molecules contain more chemical bonds.

• Because carbohydrates are less dense than fats.

• Because fats are easier to digest than carbohydrates.

• Because fats are stored in the body for longer periods.
