A major obstacle to obtaining useful energy from a nuclear fusion
reactor is containment of the fuel at the very high temperatures required
for fusion. The reason such high temperatures are required is to: -
ANSWER--A MAKES NO SENSE
WHY WOULD YOU USE HIGH TEMPS TO ELIMINATE THE
NULEAR FORCE
charge is always conserved no matter the carge
C- the higher density the material, the closer the nucleic are to each oter
Enantiomers can exhibit a difference in which chemical or physical
property? - ANSWER--- Enantiomers retain most properties (density,
boiling point, IR spect)
- The strong nuclear force is what holds a nucleus together, fusion would
want a strong nuclear force to hold the. protons together
Which classification of amino acids applies to the Trp residues after
photochemical modification by CCl3CO2H? - ANSWER--Carboxylic is
an acid
it is not asking about trp in general but rather the residues
Based on the passage, what most likely causes W96 to be accessible to
CHCl3 at 75°C?

Peptide bonds are broken, releasing W96.
B.
Reduction of disulfide bonds occurs.
C.
The protein unfolds and exposes W96 to the buffer.
D.
CHCl3 extracts W96 from the protein interior. - ANSWER--Passage
says: temperature which fully denatures carbonic anhydrase but leaves
its primary structure intact
primary structure= amino acids
Peptide bonds are not broke
What is the name of the ionic compound used to make Buffer B?
A.
Ammonium formate
B.
Ammonium carbonate
C.

Which chromatographic technique would most likely separate a mixture
of native carbonic anhydrase from carbonic anhydrase photochemically
modified by CCl3CO2H? - ANSWER--Passage says: Native carbonic
anhydrase also has a net charge of -2.9 at pH 8.0.
The photochemical adds carboxylic acids which are negatively charged
Pv=nrt - ANSWER--Helps you look at the relationship between
everything
4 mols of CO react to give you 2 mol of product
n is halved that mean pressure is halved bc direct relationship
0.5*1
In which phase(s) will the MCS precursor be predominantly found after
the extraction step? - ANSWER--Passage MCS is a lipophillic precursor
(it loves lipids) so it is not water soluble
When the covalent attachment to alliinase is broken, PLP is still held
rigidly in the active site by a salt bridge and a π-stacking interaction.
These interactions are most likely provided by the side chains of which
amino acids? - ANSWER--Can eliminate B and D because they do not
include pi stacking (tyrosine pi stacks)
