Amino acids Monosaccharides Fatty acids Nucleotides

Correct Answer:

Nucleotides

Question 4

The three-dimensional shape of a protein, including its biological activity, depends most directly on which level of structure being maintained?

Correct Answer:

The tertiary structure determined by interactions among R groups

Question 5

Why are carbon atoms especially well suited to form the diverse molecules that make up living organisms?

Carbon can form only single bonds, keeping molecules simple Carbon is the most electronegative element Carbon has four valence electrons and forms four covalent bonds, allowing branched, ringed, and chained structures Carbon readily forms ionic bonds with water
