Question 1

Which functional group acts as an acid when placed in solution?

Accepted Answer

A)   -OH
B)   -NH2
C)   -SH
D)   -COOH
E)   -PO4 The carboxyl group is found in amino acids and will donate a hydrogen ion to a solution resulting in the functional groups becoming -COO- and increasing the acidity of the solution.F) A) and B)
G) B) and E)

Question 2

When you eat a salad, which one of the following components will pass through the body with the least amount of digestion?

Accepted Answer

A)   dressing
B)   croutons
C)   lettuce
D)   egg
E)   bacon bits The lettuce is comprised of the structural carbohydrate called cellulose. Humans lack the enzymes needed to break the bonds apart between monomers and are thus not able to digest this material.F) C) and D)
G) B) and E)

Question 3

In addition to carbon, an organic molecule must contain

Accepted Answer

A)   nitrogen.
B)   oxygen.
C)   hydrogen.
D)   sulfur.
E)   phosphorous. Organic molecules are those that contain both carbon and hydrogen.F) C) and D)
G) None of the above

Question 4

The four main categories of organic macromolecules are

Accepted Answer

A)   monosaccharides, disaccharides, trisaccharides, and polysaccharides.
B)   proteins, DNA, waxes, and sugars.
C)   carbohydrates, lipids, proteins, and nucleic acids.
D)   RNA, DNA, steroids, and fats.
E)   lipids, starches, DNA, and protein.F) A) and D)
G) A) and E)

Question 5

In the diagram below, the monomer that serves as the subunit to creating this organic molecule category is called

Accepted Answer

A)   nucleotide.
B)   phosphate.
C)   sugar.
D)   base.
E)   glucose.F) B) and D)
G) D) and E)

Question 6

The figure below represents the formation of a ________ molecule by the process of ________. - groups of glycerol producing a fat molecule." class="answers-bank-image d-inline" rel="preload" >

Accepted Answer

A)   glycogen; hydrolysis
B)   DNA; dehydration synthesis
C)   protein; hydrolysis
D)   fat; dehydration synthesis
E)   polysaccharide; hydrolysis The removal of water allows the carboxyl units of three fatty acids to bond to the OH- groups of glycerol producing a fat molecule.F) A) and B)
G) A) and C)

Question 7

Amino acids are needed to build ________, just as ________ are needed to create DNA.

Accepted Answer

A)   protein; nucleotides
B)   fatty acid; hydroxides
C)   polysaccharides; carboxyl
D)   RNA; glucose monomers
E)   fats; sugars Amino groups are part of amino acid monomers which are the building blocks of proteins. Similarly, phosphate groups are a component of nucleotides which are the monomer building blocks to DNA molecules.F) A) and B)
G) None of the above

Question 8

Testosterone is a lipid-based hormone; insulin is a ________-based hormone.

Accepted Answer

A)   saccharide
B)   protein
C)   steroid
D)   carbohydrate
E)   nucleic acid Insulin is a regulatory protein comprised of long chains of amino acids.F) C) and E)
G) A) and B)
