Multiple Choice

Which statement correctly compares a function of lipids to a function of proteins in the body?

Both lipids and proteins primarily function as genetic information carriers.

Lipids primarily serve as long-term energy storage molecules, while proteins function mainly as enzymes and structural components.

Proteins are the main source of long-term energy storage, while lipids act as catalysts for biochemical reactions.

Lipids and proteins both serve as the primary building blocks of nucleic acids.

Verified step by step guidance

Step 1: Begin by understanding the primary functions of lipids and proteins in the body. Lipids are primarily involved in long-term energy storage, insulation, and forming cell membranes. Proteins, on the other hand, serve as enzymes, structural components, signaling molecules, and transporters.

Step 2: Evaluate the first statement: 'Both lipids and proteins primarily function as genetic information carriers.' This is incorrect because genetic information is carried by nucleic acids (DNA and RNA), not lipids or proteins.

Step 3: Evaluate the second statement: 'Lipids primarily serve as long-term energy storage molecules, while proteins function mainly as enzymes and structural components.' This is correct because it accurately describes the roles of lipids and proteins in the body.

Step 4: Evaluate the third statement: 'Proteins are the main source of long-term energy storage, while lipids act as catalysts for biochemical reactions.' This is incorrect because lipids, not proteins, are the main source of long-term energy storage, and proteins, not lipids, act as catalysts (enzymes).

Step 5: Evaluate the fourth statement: 'Lipids and proteins both serve as the primary building blocks of nucleic acids.' This is incorrect because nucleic acids are composed of nucleotides, not lipids or proteins.
