Amino acids and sugars are both required by animals to maintain their health. Without a diet containing both of these, animals cannot survive. Amino acids are obtained by animals when they digest-

• nucleic acids

• proteins

• lipids

• carbohydrates

If a complex molecule can be digested to produce monosaccharides and disaccharides, then the original molecules should be classified as which type of biomolecule?

• proteins

• nucleic acids

• lipids

• carbohydrates

Triglycerides are compounds created by combining a molecule of glycerol with three fatty acids. Triglycerides are used to store large amounts of energy and are classified as a form of which biomolecule?

• nucleic acids

• lipids

• proteins

• carbohydrates

In every living cell, DNA and RNA serve as the molecules that store and transmit genetic information throughout the cell. These molecules are both forms of which biomolecule?

• carbohydrates

• proteins

• nucleic acids

• lipids

Identify this molecule: Used to make a cell membrane, nonpolar, not a polymer

• carbohydrates

• lipids

• proteins

• nucleic acids

A primary difference between nucleic acids and carbohydrates is that only the nucleic acid is able to-

• transit information

• store chemical energy

• be classified as a polymer

• be used to create cell walls

Which of the following molecule would be considered an organic compound?

• water (H2O)

• methane (CH4)

• salt (NaCl)

• rust (Fe2O3)
