Integral membrane Protein :

Integral membrane proteins are found in the bilayer membranes that enclose cells and organelles and are essential for molecular movement, energy transmission, and signal transduction.
Integral membrane proteins, also known as intrinsic proteins or transmembrane protein, have domains on both sides of the membrane and one or more segments that are permanently lodged within the phospholipid bilayer.
Integral proteins are cell membrane proteins that include hydrophilic and hydrophobic domains and are totally encapsulated in the phospholipid bilayer.
Some of the integral proteins include channel proteins and carrier proteins.
Their primary job is to open up the phospholipid bilayer, which restricts the passage of polar and large molecules, across the membrane. They serve as the entrance, facilitating easier active or passive transit.
