Answer #1

The membrane spanning region of integral membrane protein is composed of non-polar amino acids which are very strongly bound to the mebrane and are broken by non- polar solvents or detergents. The peripheral proteins contain polar amino acids and these are bound to integral proteins of the membrane through hydrophobic, electrostatic or covelent bonds.

Hence, option A is correct.
