Answer :

The energy stored in each of these macromolecules varies because their chemical structures, and therefore their energy-storing bonds,differ.

Macromolecules differ in the amount of energy they contain because they possess different chemical structures.

MACROMOLECULES:

  • Macromolecules, also called biomolecules are organic molecules made up of combination of simpler units.

  • Macromolecules include:
  1. proteins
  2. lipids
  3. nucleic acids
  4. carbohydrates

  • Macromolecules have the ability to store energy in their chemical bonds.

  • However, different macromolecules contain different amounts of energy and this can be attributed to the different chemical structures of each macromolecule.

  • The chemical structure of a macromolecule will determine the amount of energy that macromolecule can hold.
