Multiple Choice

Which of the following best describes how amino acids are similar to carbohydrates and lipids?

They all function primarily as genetic information carriers.

They all contain a central carbon atom bonded to an amino group and a carboxyl group.

Verified step by step guidance

Step 1: Begin by analyzing the question to understand the comparison being made between amino acids, carbohydrates, and lipids. The goal is to identify a shared characteristic among these biomolecules.

Step 2: Recall the primary functions of amino acids, carbohydrates, and lipids. Amino acids are the building blocks of proteins, carbohydrates serve as energy sources and structural components, and lipids are key components of membranes and energy storage molecules.

Step 3: Evaluate the options provided in the question. Option 1 suggests they function as genetic information carriers, which is incorrect because this role is primarily associated with nucleic acids (DNA and RNA).

Step 4: Option 2 states that they all contain a central carbon atom bonded to an amino group and a carboxyl group. This is specific to amino acids and does not apply to carbohydrates or lipids, so this option is incorrect.

Step 5: Option 3 correctly identifies that amino acids, carbohydrates, and lipids all serve as building blocks for larger macromolecules in the cell. Proteins are made from amino acids, polysaccharides are made from monosaccharides, and lipids form structures like membranes. This is the correct answer.
