2. Resistance to antibiotics results from variations in the genetic code of Streptococcus pneumoniae.

Which type of molecule encodes genetic information in Streptococcus pneumoniae?

• carbohydrates

• nucleic acids

• proteins

• fatty acids

4. In living organisms, lipids function mainly as:

• Sources of stored energy and transmitters of genetic information

• Sources of stored energy and components of cellular membranes

• Transmitters of genetic information and catalysts of chemical reactions

• Catalysts of chemical reactions and components of cellular membranes

Which macromolecule makes up the majority of the cell membrane?

• nucleotide

• lipid

• protein

• carbohydrate

Baby food manufacturers sometimes use proteases in their products. Proteases catalyze the

breakdown of the proteins in these foods, making digestion easier for infants.

Proteases are which of the following types of molecules?

• enzymes

• fatty acid

• carbohydrates

• nucleic acid

Many plants have waxy coatings on some surfaces. This coating reduces water loss because it is

not water-permeable. This waxy coating is which of the following types of organic molecule?

• proteins

• carbohydrates

• nucleic acid

• lipids

Like complex carbohydrates, proteins are macromolecules that serve many functions and can be

chemically broken down and restructured. Both proteins and complex carbohydrates are which of the

following?

• polymers of smaller subunits

• sequence of sugars

• lipids of large molecules

• nucleotides of DNA

What is the function of macromolecule subunit below?

• energy

• catalyst

• stores genetic information

• composes the majority of the cell membrane

Which types of organic molecules serve as the

building blocks of living things and form when

amino acids are joined by a peptide bond?

• proteins

• fatty acids/lipids

• carbohydrates

• nucleic acids
