Question

Integral proteins of cell membrane are
(A) Found only on the outer surface of the membrane
(B) Partially or totally burried in the membrane
(C) Easily removed from membranes
(D)
Found only on the inner surface of membrane​

Answer 1

Integral membrane proteins, also called intrinsic proteins, have one or more segments that are embedded in the phospholipid bilayer. Most integral proteins contain residues with hydrophobic side chains that interact with fatty acyl groups of the membrane phospholipids, thus anchoring the protein to the membrane.

Answer 2

Answer:

The answer is a option Partially or totally burried in the membrane
