Determination of the tertiary structure of a membrane protein finds that the outer surface is composed primarily of hydrophobic residues. which conclusion is most likely from this observation?

The hydrophobic residues functions as a binding agent for the protein to the membrane

Explanation:

The membrane is a phospholipid bilayer that consists primarily of fatty acetyl groups. The protein has hydrophobic side chains that interacts with those fatty acetyl groups, forming a bond that will basically have the the protein anchored to the phospholipid bilayer membrane.

explanation:

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
