Macromolecules Quiz

What is the primary function of carbohydrates in living organisms?

• Building cell walls

• Regulating body temperature

• Storing genetic information

• Source of energy

Describe the structure of a lipid molecule and its role in the body.

• Lipid molecules have a hydrophobic head and a hydrophilic tail, and they play a role in transporting oxygen in the blood.

• Lipid molecules have hydrophobic hydrocarbon chains and a hydrophilic head, and they play a role in cell membranes, energy storage, and insulation.

• Lipid molecules have a hydrophilic hydrocarbon chain and a hydrophobic head, and they play a role in muscle contraction.

• Lipid molecules have a hydrophilic head and a hydrophobic tail, and they play a role in maintaining bone structure.

How do carbohydrates provide energy to the body?

• Sugars like glucose are broken down to produce fast energy for cells

• Protein is used as the primary source of energy for the body.

• Lipids are used as the primary source of energy for the body.

• Carbohydrates are stored as fat and not used for energy.

Explain the difference between saturated and unsaturated fats and their impact on health.

• Saturated fats have a positive impact on heart health, while unsaturated fats are linked to heart disease.

• Saturated fats and unsaturated fats have the same impact on heart health.

• Saturated fats are liquid at room temperature and are linked to heart disease, while unsaturated fats are solid at room temperature and can have a positive impact on heart health.

• Saturated fats are solid at room temperature and are linked to heart disease, while unsaturated fats are liquid at room temperature and can have a positive impact on heart health.

What are the building blocks of proteins and how are they linked together?

• Fatty acids and ester linkages

• Nucleotides and hydrogen bonds

• Glucose and glycosidic bonds

• Amino acids and peptide bonds

What is the function of proteins in the body?

• Proteins provide structure, function, and regulation for the body's tissues and organs.

• Proteins help in blood circulation

• Proteins are only found in the skin

• Proteins provide energy for the body

What are the two types of nucleic acids and what are their roles in the cell?

• DNA and RNA ; provide genetic information

• ATP and ADP ; provide genetic information

• Carbohydrate and Enzyme

• DNA and RNA ; provide energy for the cells

Describe the structure of a nucleotide and its role in storing genetic information.

• A nucleotide consists of a sugar, a lipid group, and a nitrogenous base. It stores genetic information in the sequence of its lipids, which form the genetic code.

• A nucleotide consists of a sugar, a phosphate group, and a nitrogenous base. It stores genetic information in the sequence of its nitrogenous bases, which form the genetic code.

• A nucleotide consists of a protein, a phosphate group, and a nitrogenous base. It stores genetic information in the sequence of its phosphate groups, which form the genetic code.

• A nucleotide consists of a sugar, a phosphate group, and a nitrogenous base. It stores genetic information in the sequence of its sugar, which form the genetic code.

How do nucleic acids contribute to the process of protein synthesis?

• By providing energy for protein synthesis

• By converting proteins into nucleic acids

• By inhibiting the process of protein synthesis

• By providing the genetic information for protein synthesis

The monomers for carbohydrates are _______________.
