Which of the following proteins is likely to have quaternary
structure? correct answer: A multimeric protein that contains
multiple peptide chains
Prosthetic groups are complex nonprotein molecules that
participate in catalysis by providing functional groups that form
a covalent intermediate between the enzyme and the substrate.
Which of the following is an example of a coenzyme or cofactor
that participates in a covalent catalysis reaction? correct answer:
Pyridoxal phosphate
Which of the following best describes a protein domain? correct
answer: A section of a protein structure sufficient to perform a
particular chemical or physical task
Cleavage of fructose 1,6 bisphosphate to dihydroxyacetone and
Glyceraldehyde 3-phosphate involves the breaking of a carbon-
carbon bond through a process other than oxidation or
hydrolysis. This is achieved by what class of enzymes? correct
answer: Lyase
A 55-year old man is brought to the emergency room with a
chief complaint of chest pain and tingling in his left arm.
Elevation of which of the following enzymes in circulation
would be most indicative of myocardial infarction? correct
answer: Troponin
, Allosteric activators of hemoglobin will increase substrate
binding through which of the following mechanisms? correct
answer: Binding the protein, and keeping it in the "R"
conformation
Which of the following best describes tertiary structure? correct
answer: Interactions between alpha helices and beta sheets to
form a domain
How do most enzymes reduce the activation energy needed to
move a reaction forward? correct answer: providing an active
site most complementary to the transition state
Domains are common structural elements that retain a particular
function within the protein. Which of the following is an
example of a protein domain? correct answer: An arrangement
of beta-strands connected by alpha-helices (beta-alpha-beta-
alpha)
Which amino acid would not be commonly found in the middle
of an alpha-helical domain? correct answer: Proline
Which of the following is a true statement with regards to the
malate-aspartate shuttle system? correct answer: Generates 2.5
molecules of ATP in mitochondria per each NADH from
glycolysis.
Complex II (Succinate Q-reductase) is not considered part of the
process of oxidative phosphorylation because it is unable to do
