α-helices and β-sheets are primarily stabilized by which of the following interactions? hydrogen bonding Domains are common structural elements that retain a particular function within the protein. Which of the following is an example of a protein domain? An arrangement of β-strands connected by α-helices (βαβαβ) How do most enzymes reduce the activation energy needed to move a reaction forward?

Primary protein structure Linear sequence of amino acids in polypeptide chain. Written from amino (N) terminus to the carboxyl (C) terminus Secondary protein structure is made up of a-helix b-pleated sheets a-helix Carbonyl group of peptide bond forms a hydrogen bond with the amide nitrogen of another peptide bond four amino acids down the polypeptide chain a-helix structure is highly Compact and rigid a-helix composes how many secondary structures? 1/3 Which amino acid is not fo...

Which of the following best describes a protein domain? A section of a protein structure sufficient to perform a particular chemical or physical task If a mutation is made within the active site of an enzyme resulting in an increase in Km, which of the following will be true with respect to the enzyme kinetics? the enzyme will require a higher substrate concentration to reach 1/2 Vmax The following represents a series of reactions. As levels of B increase, this will decrease the conversion...
