Question

which one of the following is correctly matched?
cho - corba
cho - i ipids
chon - nucleic acids
chop - proteins

cho - carbs
cho - lipids
chon - nucleic acids
chonp - proteins

cho - carbs
cho - nucleic acids
chon - lipids
chop - proteins

cho - carbs
cho - lipids
chon - proteins
chonp - nucleic acids

Explanation:

Carbohydrates (Carbs) are composed of Carbon (C), Hydrogen (H), and Oxygen (O), so CHO - Carbs is correct. Lipids are mainly C, H, O (some have other elements in certain lipid types like phospholipids having P, but basic lipid structure is CHO). Proteins are made of Carbon (C), Hydrogen (H), Oxygen (O), Nitrogen (N) (some have S etc., but core is CHON). Nucleic Acids are composed of Carbon (C), Hydrogen (H), Oxygen (O), Nitrogen (N), and Phosphorus (P), so CHONP - Nucleic Acids.

Answer:

CHO - Carbs, CHO - Lipids, CHON - Proteins, CHONP - Nucleic Acids (assuming the last option in the last set of choices is the intended correct one as per the analysis of macromolecule composition)
