Question

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.

Answer 1

Answer:

Sugar molecules do NOT provide all the elements needed to make the four types of macromolecules.

Explanation:

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.
