In a protein analysis, what is the purpose of using NaKC4H4O6
(Potassium sodium tartrate) in Biuret reagent? Please also explain
the roll of a buret reagent in a rxn. Thanks
Describe the function of the sodium/potassium ATPase. a. What
does the protein/molecule itself do?(3 points) b. How does the
function of this one protein/molecule play a role in homeostasis of
the whole body? Describe at least three specific, unique ways.
For
each of the three assays (Bradford, Biuret, Folin-Ciocalteu)
indicate what part of the protein reacts with the color forminh
reagent and how does this specifically detect protein in a
sample
4. The movement of sodium and potassium ions via sodium channel
and potassium channel proteins is
A. Active Process B. Passive process C. Both D. None of the
above
5. The Na/K voltage gated channel protein uses __________ to
move sodium and potassium across the plasma membrane.
6. The ion, which conduct electricity, is:
a. A charged atom b. a charged molecule c. Both A and B are
correct d. none of these are correct
7. In a resting membrane...
I'm calculating the equilibrium potentials of sodium
ions and potassium ions using the Nernst equation. In the problem I
just did, I calculated Ena= +69.9 mV and Ek=-92.0 mV.
The next part of the question asks, "If the conditions
are the same as above, at which membrane potential would you expect
the movement of the Na and K ions to cancel each other out and
there be no net change in membrane potential?"
Do I average their equilibrium potentials or...
what is the chemical principle of the Biuret assay (i.e. what
reacts with what)? Are there any known interferences or biases in
this assay? Draw a scheme of the biuret reaction
Describe what kind of membrane proteins are involved in (1)
maintaining the sodium and potassium concentrations inside a neuron
cell and (2) generating an action potential?
