Answer 1

Answer: Integral membrane proteins.

Integral membrane proteins are named so because they are the integral components of the membrane. They cross the plasma membrane ( hydrophobic phospholipid bilayer) one or more times and impart specific function to it.  The part of the protein embedded in the bilayer is called as alpha-helical region and is mainly composed of hydrophobic amino acids.

Example- $Na^{+} K^{+} ATPase$
