Exploring Biological Molecules

What are the primary functions of carbohydrates in living organisms?

• The primary functions of carbohydrates are to provide energy, serve as structural components, and facilitate cell recognition and signaling.

• To store genetic information

• To provide insulation and protection for cells

• To act as enzymes in metabolic reactions

How do amino acids contribute to the structure and function of proteins?

• Amino acids contribute to the structure and function of proteins by forming polypeptide chains that fold into specific shapes, determining the protein's function.

• Proteins are made up of nucleotides that determine their function.

• Amino acids do not influence the shape of proteins at all.

• Amino acids are only used for energy production in the body.

What are the main roles of lipids in biological systems?

• Lipids are only involved in the transport of oxygen in the blood.

• Lipids are primarily responsible for protein synthesis.

• The main roles of lipids in biological systems are forming cell membranes, energy storage, signaling, and insulation.

• Lipids are the main components of nucleic acids.

Describe the structure of nucleic acids and their importance in genetics.

• Nucleic acids are made of amino acids that provide energy to cells.

• Nucleic acids are simple sugars that help in digestion.

• Nucleic acids are polymers of nucleotides that store and transmit genetic information, essential for protein synthesis and cellular regulation.

• Nucleic acids are proteins that regulate metabolic processes.

How do enzymes facilitate chemical reactions in the body?

• Enzymes facilitate chemical reactions by lowering activation energy and stabilizing transition states.

• Enzymes increase activation energy to speed up reactions.

• Enzymes are consumed in the reactions they catalyze.

• Enzymes change the products of the reactions they facilitate.
