Detailed explanation-1: -Integral proteins are embedded in the phospholipid bilayer, and also called transmembrane proteins. Often times these integral proteins serve as channels through which molecules move across the cell membrane.
Detailed explanation-2: -Integral membrane proteins are embedded directly within the lipid bilayer. Peripheral membrane proteins are not inserted into the lipid bilayer but are associated with the membrane indirectly, generally by interactions with integral membrane proteins.
Detailed explanation-3: -Integral proteins are also called intrinsic proteins which remains embedded in the phospholipid bilayer.
Detailed explanation-4: -Integral membrane proteins are permanently embedded within the plasma membrane. They have a range of important functions. Such functions include channeling or transporting molecules across the membrane. Other integral proteins act as cell receptors.
Detailed explanation-5: -An integral, or intrinsic, membrane protein (IMP) is a type of membrane protein that is permanently attached to the biological membrane. All transmembrane proteins are IMPs, but not all IMPs are transmembrane proteins. IMPs comprise a significant fraction of the proteins encoded in an organism’s genome.
