Which macromolecule is used as our main source of energy?

• Nucleic Acids

• Lipids/fats

• Proteins

• Carbohydrates

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 ( what they are composed of)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.

Protein is found in...

• DNA

• Olive Oil

• Bread

• Steak

Answer explanation

Steak and other meats (and animal products like eggs) are wonderful sources of proteins.

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!
