Biomolecules

What is the role of lipids in the body?

• Lipids provide insulation, store energy, and make up cell membranes.

• Lipids are primarily responsible for transporting oxygen in the blood.

• Lipids are the main source of immediate energy for the body.

• Lipids help in the digestion of carbohydrates.

What role do proteins play in the body?

• Proteins are primarily used for energy storage.

• Proteins are essential for building and repairing tissues, making enzymes, and supporting immune function.

• Proteins are mainly involved in the transport of oxygen in the blood.

• Proteins are responsible for the production of hormones only.

What are enzymes?

• Enzymes are carbohydrates that provide energy to the body.

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

• Enzymes are lipids that store genetic information.

• Enzymes are minerals that help in muscle contraction.

What are carbohydrates made of?

• Carbon, hydrogen, and oxygen

• Nitrogen, hydrogen, and oxygen

• Carbon, sulfur, and hydrogen

• Phosphorus, carbon, and nitrogen

What is a simple carbohydrate?

• A type of protein that provides energy

• A sugar that is quickly absorbed by the body, such as glucose or fructose

• A complex carbohydrate found in whole grains

• A fat that is solid at room temperature

What is the function of nucleic acids?

• To store and transmit genetic information.

• To provide energy for cellular processes.

• To act as enzymes in biochemical reactions.

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 a biomolecule?

• A small molecule that is not essential for life.

• A large molecule that is essential for life, including proteins, nucleic acids, carbohydrates, and lipids.

• A type of vitamin that helps in metabolism.

• A synthetic compound used in pharmaceuticals.

What is an organic compound?

• A compound that contains only hydrogen and oxygen.

• A compound that contains carbon and is associated with living organisms.

• A compound that is found only in minerals.

• A compound that does not contain carbon.
