12,12,12 - ANS - In the carbon reduction phase of the C3 cycle, the production of
12 G3P molecules requires _ 3-PGA molecules and the use of _ ATPs and _
NADPHs.
A)
B)
C)
D)
E)
\18 - ANS - A 12-carbon fatty acid is processed via beta oxidation into 6
acetyl-CoA molecules, each of which then enter into the citric acid cycle. How
many molecules of NADH would be produced b these 6 turns of the citric acid
cycle?
\2 acetyl Coa + 2CO2 + 2NADH - ANS - Oxidative decarboxylation of 2 pyruvates
at the pyruvate dehydrogenase complex yields...
A) 2 G3P
B) 2 acetyl CoA + 2 CO2 + 2NADH
C) 1 acetyl CoA + 1 ATP
D) 1 ATP + 1 CO2 + 1 NADH
E) 2 ATP + 2 CO2 + 2 NADH
\46, 23 - ANS - In most cases, an animal with a diploid number of 2n=46
chromosomes will have _ chromosomes in its diploid somatic (body) cells and _
chromosomes in its gametes.
\8 - ANS - Suppose that a cell has 16 chromatids at prophase of mitosis. After
mitosis and cytokinesis end, the 2 resulting daughter cells should have how
many chromosomes each?
\A competitive inhibitor - ANS - The conversion of citrate to isocitrate is catalyzed
by a specific enzyme. When oxaloacetate is introduced to a solution containing
the enzyme and a saturating concentration of citrate the rate of the reaction
decreases. Adding more citrate partially overcomes the effect of oxaloacetate on
the reaction rate. Further studied reveal that oxaloacetate binds to the enzyme at
the same location that citrate does. Also, it binds reversibly, allowing the enzyme
to be fully functional if oxaloacetate is removed from the solution. In this situation
oxaloacetate is acting as:
\a phosphorylated intermediate is often produced - ANS - When ATP hydrolysis is
used in a coupled reaction to provide energy:
