Which of the following is NOT true of protein quaternary structure?

1 answer:

3 0

The choices for this question can be found elsewhere and as follows:

A. A single polypeptide may have quaternary structure.
B. Hydrogen bonds may hold the polypeptides in contact.
C. A quaternary protein cannot have fewer than two carboxyl groups.

I think the correct answer from the choices is option A. The statement a single polypeptide may have quaternary structure is not true.

Answer:

Cl^-<NO3^-<H2O<F^-<CN^-

Explanation:

When we talk about base strength we are referring to how easily a chemical specie accepts protons.

The greater the ability of a specie to accept H^+, the greater its base strength.

The order of increasing base strengths of the species listed are shown in the answer above.

In a titration, 25.0 mL of 0.500 M KHP is titrated to the equivalence point with NaOH. The final solution volume is 53.5 mL. Wha

Lena [83]

M1v1=m2v2
m2=(m1v1)/v2
Where m is the molarities and v is the volumes
m2=(25.0*0.500)/53.5
m2=12.5/53.5
m2=0.2336
by rounding off:
m2=0.234 M
so the answer is C: 0.234 M
