Questions and Answers

What is the primary structure of proteins?

  • A secondary structure resembling a coiled spring
  • The order in which amino acids are linked together in a protein (correct)
  • The arrangement in space adopted by the backbone portion of a protein
  • The structure formed by hydrogen bonds between protein chains

Hydrogen bond formation between two molecules is possible when:

  • One molecule has a hydrogen atom attached to an atom of nitrogen, oxygen, or fluorine, and the other molecule has a nonbonding electron pair on a carbon atom (correct)
  • Both molecules have hydrogen atoms attached to carbon atoms
  • Both molecules have nitrogen, oxygen, or fluorine atoms with nonbonding electron pairs
  • One molecule has a hydrogen atom attached to an atom of nitrogen, oxygen, or fluorine, and the other molecule has a carbon atom

In proteins, what does the secondary structure refer to?

  • The arrangement in space adopted by the backbone portion of a protein (correct)
  • The linear sequence of amino acids linked together
  • The overall 3D shape of the folded protein
  • The arrangement of multiple protein chains held together by hydrogen bonds
