Question

Identify the four main categories of macromolecules in a cell from the below options?

• A. Proteins, DNA, RNA, and steroids
• B. Monosaccharides, lipids, polysaccharides, and proteins
• C. Proteins, nucleic acids, carbohydrates, and lipids
• D. Nucleic acids, carbohydrates, monosaccharides, and proteins.

Answer 1

The correct option is C

Proteins, nucleic acids, carbohydrates, and lipids

Macromolecules are very large molecules (greater than about 5000 daltons) made as polymers of subunits in an exact sequence. Living cells contain three major classes of macromolecules: (1) nucleic acids, polymers of nucleotides; (2) proteins, polymers of amino acids; and (3) polysaccharides, polymers of sugars and (4) Lipids
