Define biomolecules.

• Biomolecules are inorganic compounds that are not essential for life.

• Biomolecules are organic molecules that are essential for life, including carbohydrates, proteins, lipids, and nucleic acids.

• Biomolecules are synthetic compounds used in pharmaceuticals.

What is the difference between saturated and unsaturated fats?

• Saturated fats have no double bonds between carbon atoms, while unsaturated fats have one or more double bonds.

• Saturated fats are liquid at room temperature, while unsaturated fats are solid.

• Saturated fats contain more calories than unsaturated fats.

• Saturated fats are healthier than unsaturated fats.

What is the primary function of carbohydrates?

• To provide energy to the body.

• To store genetic information.

• To act as enzymes in biochemical reactions.

What are lipids primarily used for in the body?

• Energy storage, insulation, and making up cell membranes.

• Transporting oxygen in the blood.

• Producing hormones and enzymes.

• Breaking down carbohydrates for energy.

What is the function of enzymes?

• Enzymes are proteins that act as catalysts to speed up chemical reactions in the body.

• Enzymes are carbohydrates that provide energy to cells.

• Enzymes are lipids that store genetic information.

• Enzymes are minerals that help in muscle contraction.

What is a polymer?

• A small molecule that cannot be broken down into simpler substances.

• A large molecule made up of repeating structural units (monomers) connected by covalent bonds.

• A type of chemical reaction that forms new compounds.

• A mixture of different types of molecules.
