A ____________________ is a large molecule.

• Micromolecule

• Macromolecule

• Amino Acid

• Monosaccharide

Answer explanation

Macro= large, micro=small

Which of the following elements are found in all macromolecules?

• 
• 
• 
• 

Answer explanation

Carbon, hydrogen, oxygen are all part of every macromolecule. Only Nucleic acids and proteins contain nitrogen.

A __________________ is a large molecule made of many small ones.

• Monomer

• Dissacharide

• Polymer

• Sugar

Answer explanation

Poly means many- so a polymer is many molecules linked together.

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?

• Nucleic Acids

• Lipids/fats

• Proteins

• Carbohydrates

Answer explanation

We use carbohydrates as our energy source. We break down the carbohydrates into smaller, simpler sugars, which we can absorb and use for energy.

Which of the following is an example of carbohydrates?

• Steak

• Olive oil

• Bread

• DNA

Answer explanation

Bread, sweets, rice, grains, veggies, fruits, etc. are all great sources of carbohydrates!

_______________ 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.

Which macromolecule stores energy?

• Carbohydrates

• Proteins

• Lipids/Fats

• Nucleic Acids

Answer explanation

Lipids (fats) store energy. They provide energy later in case we have to go without food.

The monomer of proteins is...

• Polymers

• Monosaccharides

• Fatty Acids

• Amino Acids

Answer explanation

Proteins are made up of amino acids. When people exercise and try to build muscle, they will often take amino- which is just a fancy term for protein!

What is the monomer of nucleic acids?

• RNA

• DNA

• Nucleotides

• Nucleic pieces

Answer explanation

Nucleic acids are made of smaller pieces called nucleotides.
