What type of protein, embedded in the plasma membrane, aids reactions of molecules that arrive?

The plasma membrane has a type of protein called intrinsic integrals that are embedded in the thickness of the bilayer and moves laterally in the membrane and act on arriving molecules. Their separation results in the destruction of the membrane structure, this protein is the opposite of the peripheral protein and act as filters and mechanisms of active transport in the nutrients and wastes that are expelled outside the cell.

If the experiment was perfomed more then once and you get the same results
