Question

Smaller organic molecules such as glucose or amino acids can be combined into larger macromolecules. What do we call the smaller molecules from which the macromolecules are built? 1) Ionic compounds 2)fatty acids 3)polymers 4)monomers 5) polar molecules

Answer 1

Answer:

4. Monomers

Explanation:

Monomers are small and simpler substances that are bonded together to form large and complex polymers. Many amino acids are bonded by a peptide linkage to form complex polypeptides. Here, amino acids are the monomers while the polypeptides are the polymers. Glucose molecules are bonded by a glycosidic linkage to form cellulose or starch or glycogen. Here, glucose is a monomer while cellulose, starch, and glycogen are the polymers. Therefore, macromolecules are made up of monomers.
