Question

Does sugar molecules provide all of the elements needed to make the four types of macromolecules

Answer 1

No, sugar molecules alone do not provide all of the elements needed to make the four types of macromolecules. While sugar molecules (specifically, monosaccharides) are a source of carbon, hydrogen, and oxygen, they do not provide all of the other elements required to make proteins, nucleic acids, lipids, and carbohydrates. These macromolecules require additional elements such as nitrogen, phosphorus, and sulfur that are not present in sugar molecules.
