Here are the matches for each type of complex molecule from Column A to the type of simpler molecule in Column B:
- carbohydrates: a. simple sugars
- nucleic acids: d. nucleotides
- lipids: b. fatty acids
- proteins: c. amino acids
So the correct pairs are:
- Carbohydrates → Simple sugars
- Nucleic acids → Nucleotides
- Lipids → Fatty acids
- Proteins → Amino acids
