1) If the lipid bilayer in Section B represents the plasma membrane, which part of the protein is the cytoplasmic domain?

There is no way to tell which is the cytoplasmic domain with the information given.
Section A is the cytoplasmic domain since it contains disulfide bonds.
Section C is the cytoplasmic domain since the N-terminus is always found in the cytoplasm.
Section C is the cytoplasmic domain since glycosylation cannot occur on the cytoplasmic domain.
Section B is the cytoplasmic domain since it is an alpha-helix.

2) Which type of amino acids is most commonly found in Section B?

Hydrophilic

Hydrophobic

There is no way of knowing which type of amino acids is most commonly found in Section B with the given information

3) If the lipid bilayer in Section B represents the ER membrane, which part of the protein is found INSIDE the ER (in the ER lumen)?

The entire protein must be inside the lumen of the ER.
Section C is inside the ER lumen.
Section B is inside the ER lumen.
Section A is inside the ER lumen.
All sections are equally likely to be in the ER lumen.
