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?A.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.Ammonium bicarbonate D.

Ammonium acetate - ANSWER- formate: hco2 2 / 3

carbonate: Hco3-

bicarbonate: hco3-

acetate: ch3cooh

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

• 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) Now between Asp and Arg.
