Use evidence from the diagrams of macromolecules and information provided earlier to revise your explanation about whether sugar molecules provide all the elements needed to make the four types of macromolecules.

This is because proteins, and amino acids need more types of elements than carbohydrates and lipids do. In nucleic acids, the elements are carbon, hydrogen, oxygen, nitrogen, and phosphorus. Notice that sugar molecules do not have either nitrogen or phosphorus. This same principle applies to proteins, which the elements of it are carbon, hydrogen, oxygen, and nitrogen.

All the elements needed to make the four types of macromolecules cannot be gotten from only sugar molecules.

Macromolecules are those biological molecules that are essential for life. There are four main types of these molecules and they include:

Protein

Carbohydrates

Lipids and

Nucleic acids.

All the above mentioned macromolecules have carbon, hydrogen and oxygen in their chemical structure with an exception of nucleic acids and proteins which contains nitrogen as an additional molecule.

From the diagram attached, the chemical structure of the sugar molecule shows that it's made up of carbon, oxygen and hydrogen atoms only.

Because there is no nitrogen in the sugar molecule, it cannot provide all the elements needed to make the four types of macromolecules.
