Biochemistry 301 - Exam 3
MCQs with 100% correct
answers (graded A+)
"Mad Hatters" were mad because of what? - answer heavy metal
poisoning
Using the "E1, E2, E3" terminology for Pyruvate DH Complex - TPP is
found at the active site of which enzyme? - answer E1
If carbon one (the carboxyl carbon) of Pyruvate is labeled with
carbon-14, and then the Pyruvate is put through one "turn" of the
Citric Acid Cycle, which carbon(s) of Oxaloacetate will be labeled?
Pick as many choices as are necessary. - answer none, it is lost as
CO2
"Substrate Level Phosphorylation" means making triphosphates
(ATP or GTP) just using enzymes, and not using electron transport.
The only example n the Citric Acid Cycle is catalyzed by: - answer
Succinyl CoA Synthetase
An important factor in the linkage between electron transport and
proton pumping is the fact that one molecule can easily move
hydrogen across the mitochondrial membrane - namely - answer
Ubiquinone
"Sugar can make you fat, but fat can't make you sweet" is true of
humans, but not of organisms that have what? - answer the
Glyoxalate cycle
Cyanide blocks what? - answer Complex IV
, The simplest Iron-Sulfur clusters just require a protein with a cavity
lined with residues of which amino acid residue? - answer cys
Complex IV delivers electrons from cytochrome c to O2 one at a
time, producing peroxide and superoxide in the process - answer
False
The Pentose Phosphate Pathway is most active in which tissue? -
answer adipose
The "Thirty Carbon Reaction" refers to conversion of 6 Ribose-5-P to
5 Fructose-6-P and the reverse of that, with no decarboxylations.
This conversion would utilize - answer only the non-oxidative branch
of PPP
Most tissues in the human body use the Glycerol Phosphate Shuttle.
What organs use the Malate Aspartate Shuttle instead? - answer
Heart, liver
If Fructose-6-P and Erythrose-4-P were reacted with Transketolase
and TPP in the lab, what sugars would result? - answer Erythrose-4-
P and Fructose-6-P
The mechanism of Transaldolase is about the same as Aldolase. But
the mechanism of Transketolase involves covalent attachment of
substrate to - answer Thiamine Pyrophosphate
Pamaquine-Induced Hemolytic Anemia is caused by a deficiency of -
answer G6PDH
