says it is composed of flavin
structure is a nucleotide base
structure B could be
What is the chemical structure C also could be
structure of a component structure D is an amino acid
found in four of the five down between B and C
cofactors used by Na+- to help, look at the captioned note on the table. it says Fl
NQR? represents flavin which is the redox active center in four
of the five cofactors of Na+-NQR
C has an uniquinone AND HERE IS IS MENTIONED THAT
UNIQUINONE IS IS A SUBSTATE
What is the ratio of cation to cation : enzyme
enzyme in the passage says Na+NQR was diluted to a final
spectroelectrochemical concentration of 0.75 mM in 0.150 molar of the cation
experiments described in ions
the passage? cation .15 M:
Conservation of energy, it is not created nor destroyed
The reaction between
but merely changes forms
NADH and ubiquinone is
exergonic, but the reaction,
A. Is not possible, Even if it was heat generation would
when catalyzed by Na+-
be larger for a catalyzed rection.
NQR, does not generate
C. is impossible, reactants have to be close together to
much heat in vivo. What
react
factor accounts for this
The movement of a charged particle against its
difference?
concentration gradient is energetically costly.
,Two open flasks I and II pressure=pgh
contain different volumes of g=10
the same liquid. Suppose p= density (same liquid so same density)
that the pressure is h= 10 cm
measured at a point 10 cm both have same height so pressure will be the same-- if
below the surface of the heights were different pressure would be different
liquid in each container.
How will the pressures
compare?
Question If there is a net dipole it is polar
Which of the following
substances is polar?
Question pv=nrt
If all else is held constant,
which of the following
changes would NOT double
the volume of a gas?
86Kr+ laser
What is the number of 86= mass
neutrons in the nucleus of Kr has proton number as 36
the atom used to produce 86-36=50
laser radiations? the cation or anion charge with any element is indicative
of the charge aka electron count
What is the molecular passage says its a tetra pyrrole so there are 4 carbons
formula of the heterocyclic
aromatic compound
pyrrole?
Maybe if you read the passage for once in your life and
The radiation of wavelength
not get confident then maybe you wouldn't have to take
605 nm CANNOT be used
the exam for a third time
to produce the
fluorescence radiations
Not D because look at the passage
depicted in Figure 3
not C because of E=hc/lambda (high wavelength low
because:
energy)
, Approximately how many Have to recognize STP conditions of 0 C and 1 atm (22.4
moles of Kr+ are contained L)
in the laser tube at 0°C and Volume in PV=nrt is in L
1 atm? 1cm^3=1mL
The CD spectroscopy signal look for what is chiral
that was used to generate B is not
the data in Figure 1 arises C is not
from the chirality of the: D- most beta carbons are not chiral
Samples from various time - For proteolysis, the protein is expected to be broken
points of the proteolysis of up over time
TPMTwt were subjected to - Small fragments will travel faster in the SDS-PAGE
SDS-PAGE under reducing A and B show that they are building up or oligermizing
conditions. Which figure
best depicts the expected
appearance of the gel?
If the combined mass of the Passage says that TPMT is an enzyme (methyltransferase)
TPMT substrate and can also think about the conservation of mass
cofactor was determined balance equation on products and reactants
before the enzymatically
catalyzed reaction and then
compared to the combined
mass of the product and the
cofactor after the reaction,
the net change in molecular
weight will be:
The structure of Compound - Compound 2 helped extract the receptor
2 is shown. - Receptor is MPR (progesterone) steroid is hydrophobic
so probably has to do someting with that
Compound 2
What structural feature(s)
is(are) most important to the
functioning of this
compound as described in
the passage?
