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?
A)It is a lipid-anchored membrane protein.
B)It is an integral protein.
C)The protein must be involved in passive transport.
D)The protein can undergo transverse diffusion.
