BIOC 3022 Final Exam Questions With Complete Solutions
Chloroplast ETC vs. Mitochondria ETC Correct Answers
photosystem II = complex I
plastoquinone = coenzyme Q
cytochrome b6/f = complex III
plastocyanin = cytochrome c
photosystem I = complex IV
ferrodoxin = none (somewhat similar to cytochrome c)
FNR (ferrodoxin NADP + reductase) = none
ATP synthase = ATP synthase
Glycolysis can provide cells with a variety of 6 and 3 carbon
sugars, how are 5-carbon sugars generated? Correct Answers
Pentoses are made by decarboxylation of glucose-6P in the
pentose phosphate pathway
HIV gene: env Correct Answers Function: gp120, gp41
HIV gene: gag Correct Answers Function: core, matrix, and
nucleocapsid proteins
HIV gene: pol Correct Answers Function: reverse transcriptase,
integrase, protease
HIV gene: rev Correct Answers Function: regulator of viral
expression
HIV gene: tat Correct Answers Function: transactivator of
transcription
, How are ketone bodies made? Correct Answers they are made
from AcCo-A
How are the alpha AAs of other AAs removed? Correct
Answers they are transferred onto a-ketoglutarate to make
glutamate, the enzymes used are aminotransferases specific for
each amino acid
How are the R-group nitrogens removed from Lys and Arg?
Correct Answers LYS: this is a complex multistep process
involving multiple enzymes
ARG: arginase removes 2 nitrogens as urea in the urea cycle
How does alcohol metabolism lead to excess NADH? What
problems does excess NADH cause? Correct Answers Both
alcohol dehydrogenase and aldehyde dehydrogenase produce
NADH. Excess NADH causes: hypoglycemia, diabetes, low
blood pH, elevated VLDL, fatty liver disease, kidney damage,
addiction
How does phosphocreatine make ATP? Correct Answers it
contains a high energy bond, creatine kinase, and can use it to
phosphorylate ADP
How does the chemistry of fatty acid biosynthesis compare to
that of B-oxidation? Correct Answers it is exactly the reverse
How is recombinant EPO detected? Correct Answers it is made
in prokaryotic cells, so it does not have the same glycosylation
as human EPO
Initial electron donor in chloroplast Correct Answers water
