Which of the following is not one of the four major classes of biomolecules?

• Lipids/Fats

• Carbohydrates

• Nucleic Acids

• Bacteria

• Proteins

Answer explanation

The four major macromolecules are lipids, carbohydrates, nucleic acids, and proteins.

Which macromolecule is used as our main source of energy?

_______________ are the monomers of carbohydrates.

• Monosaccharides

• Polymers

• Complex sugars

• Fructose

Answer explanation

Monosaccharides are simple sugars, like glucose, fructose, and galactose. They are linked together to make large carbohydrates.
