GENERAL HISTOLOGY

Detailed explanation-1: -Protein machineries embedded in the membranes of our cells act as ‘gatekeepers’ controlling everything transported in and out of every cell in our bodies. Because these machineries, called membrane embedded proteins, are vital to the way our bodies function they are the target of at least 40% of drugs.

Detailed explanation-2: -By acting as a gatekeeper, the plasma membrane protects the cell from its surroundings and keeps important molecules from leaving the cell, so that the correct balance of molecules is maintained.

Detailed explanation-3: -A membrane is the cell’s interface with the rest of the world-it’s gatekeeper, if you will. This phospholipid bilayer determines what molecules can move into or out of the cell, and so is in large part responsible for maintaining the delicate homeostasis of each cell.
