Membrane proteins that penetrate deeply into the lipid bilayer and can possibly extend from one surface to the other are called proteins whereas other proteins that are attached to either the inner or the outer surface of the lipid bilayer are called proteins.

Membrane proteins that penetrate deeply into the lipid bilayer and can possibly extend from one surface to the other are called _Integral_ proteins whereas other proteins that are attached to either the inner or the outer surface of the lipid bilayer are called __Peripheral___ proteins.

Explanation:

The exterior structure of plasma proteins is made up of hydrophilic components to face water while interior is made up of hydrophobic components. There are different type of proteins also found in membrane that interact with biological molecules.

regulation of gene expression. gene expression can be regulated by various cellular processes with the aim to control the amount and nature of the expressed genes. these regulatory proteins bind to dna and send signals that indirectly control the rate of gene expression
