Biomolecules

What is the role of carbohydrates in living organisms?

• Carbohydrates provide a primary source of energy for cells and are involved in structural functions.

• Carbohydrates are primarily used for storing genetic information.

• Carbohydrates are essential for the synthesis of proteins.

• Carbohydrates act as a catalyst in biochemical reactions.

What is the primary function of nucleic acids?

• To provide energy for cellular processes.

• To store and transmit genetic information.

• To act as catalysts in biochemical reactions.

• To form structural components of cells.

What is the primary source of quick energy for cells?

• Proteins

• Fats

• Carbohydrates

• Vitamins

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.

Why are lipids important for insulation?

• They provide insulation by forming a protective layer that helps maintain body temperature.

• They are a source of energy for cellular processes.

• They help in the absorption of vitamins and minerals.

• They act as a structural component of cell membranes.

What is the function of RNA in protein synthesis?

• RNA is responsible for storing genetic information.

• RNA plays a crucial role in translating genetic information from DNA into proteins.

• RNA is involved in the replication of DNA.

• RNA helps in the formation of cell membranes.

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 are the two main types of nucleic acids?

• DNA (deoxyribonucleic acid) and RNA (ribonucleic acid)

• Proteins and Carbohydrates

• Lipids and Steroids

• Amino acids and Peptides

How do lipids contribute to cell membranes?

• Lipids form a bilayer in cell membranes, providing structure and acting as a barrier to protect the cell.

• Lipids are primarily responsible for energy storage in the cell.

• Lipids help in the synthesis of proteins within the cell.

• Lipids act as signaling molecules that regulate cell division.

What are biomolecules?

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

• Inorganic compounds that do not play a role in biological processes.

• Synthetic compounds created in laboratories for research purposes.

• Simple molecules that are not essential for life.
