CORRECT ANSWERS GRADED A+
● Lipids. Answer: Composed of CHOP.
Energy-rich organic compounds, such as fats, oils, and waxes. Supply
long-term energy and are primary source of fat in the body.
● Proteins. Answer: Composed of CHON.
All are composed of the same twenty amino acids.
Make up more than 50 percent of the dry mass of cells in the body.
● Nucleic Acids. Answer: Composed of CHOPN.
DNA and RNA. The genetic information within cells that determines
what we look like. Composed of nucleotides.
● Monosaccharides. Answer: Single sugar molecule. Simplest forms of
carbohydrates. Glucose, fructose, and galactose. Examples include corn
syrup and maple syrup.
● Disaccharides. Answer: Double sugar molecules. Require some

polysaccharides.
● Polymers. Answer: Large molecules composed of many identical or
similar subunits called monomers.
● Starch. Answer: A polysaccharide formed by plants as a way to store
the large amounts of glucose produced during photosynthesis.
Animals are able to break down starch into individual glucose
molecules.
● Cellulose. Answer: A polysaccharide made up of glucose, is a very
strong material that serves as the primary structural component of plants.
Most animals are not able to break cellulose down into glucose. Is in the
food that we eat and serves as dietary fiber that regulates digestion.
● Glycogen. Answer: The polysaccharide that animals and fungi use to
store excess glucose molecules from their food.
