PCB 3023 EXAM 3 REVIEW;
QUESTIONS WITH DETAILED VERIFIED
ANSWERS; ALREADY GRADED A; 2026
3 stages of glycolysis - correct answer- 1. energy-
investment stage
2. cleavage stage
3. payoff stage
Affect of enzyme on reaction - correct answer- increased
rate
aminoacyl-tRNAs - correct answer- activated
intermediates in the formation of the peptide bond
Anabolic pathways - correct answer- Metabolic
pathways that consume energy to build complicated molecules
from simpler ones.
anaerobic respiration - correct answer- in the absence of
oxygen, pyruvate is reduced driven by the oxidation of the NADH
generated from glycolysis
,Biosynthesis is a catabolic/anabolic pathway - correct
answer- anabolic
bond found in polysaccharides that requires energy to form -
correct answer- glycosidic bond
carbon fixation - correct answer- The initial
incorporation of carbon into organic compounds.
Catabolic pathways - correct answer- Metabolic
pathways that release energy by breaking down complex
molecules into simpler compounds.
cause of gout - correct answer- deficiency in HGPRT
which causes hypoxanthine to be converted into uric acid
cause of phenylketonuria - correct answer- insufficiency
or complete lack of phenylalanine hydroxylase prevents the
conversion of phenylalanine into tyrosine causing it to
deanimate into phenylpyruvate
, Change in entropy as a reaction approaches equilibrium -
correct answer- increased entropy
Change in free energy in a spontaneous reaction - correct
answer- Negative
Coupled reactions - correct answer- pairs of chemical
reactions in which some of the energy released from the
breakdown of one compound is used to create a bond in the
formation of another compound
cristae of mitochondria - correct answer- folds of the
inner membrane
Dark reactions of photosynthesis - correct answer-
carbon fixation and the synthesis of glucose
de novo synthesis of nucleic acids - correct answer- long
pathways synthesize molecules from smaller components
Dehydration synthesis is spontaneous/nonspontaneous -
correct answer- non spontaneous
