A protein is normally found completely within the inside of a lipid bilayer. The protein likely has:
a) Mostly hydrophobic side chains, pointed outwards, with the peptide backbone on the inside.
b) Mostly hydrophobic side chains, pointed inwards, with the peptide backbone on the outside.
c) Mostly hydrophilic side chains, pointed outwards, with the peptide backbone on the inside.
d) Mostly hydrophilic side chains, pointed inwards, with the peptide backbone on the outside.
