Explanation:
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: -Proteins embedded within the phospholipid bilayer carry out the specific functions of the plasma membrane, including selective transport of molecules and cell-cell recognition.
