2. The price of a bond is generally
determined by
a. the relation between the coupon
rate and the current market rate of similar investments
b. the stated interest rate of the
bond
c. how many bonds are issued
d. who buys the bonds
3. How is the consolidated
statements treatment of constructive gain or loss on intercompany
bond investments different from the treatment of unrealized profit
on intercompany sales of inventory?
a. Constructive gain or loss is
deferred until...
Draw in detail the reaction mechanism for the acid
(H2SO4)-catalyzed esterification reaction between salicylic acid
and acetic anhydride to form aspirin. Please include an explanation
of the steps of the reaction mechanism.
Consider the mechanism of cleavage catalyzed by the enzyme
aldolase. What would be the products of the reaction if aldolase
used glucose-6-phosphate as the substrate, instead of
fructose-1,6-bisphosphate (show the structures of
glucose-6-phosphate and its products)? Based on your answer,
suggest a possible rationale for why nature chose to include two
extra steps prior to the aldolase step in glycolysis.
Consider the final reaction in the citric acid cycle, catalyzed
by malate dehydrogenase:
Malate + NAD+ ⇄ oxaloacetate + NADH + H+
Equilibrium concentrations of the reaction components were
measured as follows:
[malate] = 5.28 mM
[NAD+] = 75 uM
[oxaloacetate] = 14.5 uM
[NADH] = 14.5 uM
pH = 8.83
a) From these data calculate the equilibrium constant, Keq, for
this reaction.
b) Calculate the standard free-energy change, ΔG°’, for this
reaction (hint: remember that
the prime means that the...
In
the reaction mechanism of chymotrypsies, formation of the
tetrahedral intermediate is then followed by the formation of an
acyl enzyme Intermediate. What active site residue(s) /are
responsible for forming the first intermediate , and what type of
catalysis occurring the first step of the reaction ?
