The plasma membrane, which is also referred to as the cytoplasmic membrane, is a biological membrane that encloses the contents of the cell and separates it from the outer environment. While the side that faces the cytoplasm is the membrane’s intracellular face, the side facing outward is the extracellular face.

Which Of The Following Is True Of Integral Membrane Proteins – The plasma membrane acts as a protective barrier; however, it allows certain molecules to pass through. Basically, the membrane is selectively permeable, and it regulates the passage of substances in and out of the cell.

Many integral membrane proteins span the membrane more than once, and often many times. Either terminus may be inside or outside the cell. Proteins with multiple transmembrane domains include a large family of G-protein-coupled receptors such as rhodopsin, the coloured visual pigments, and receptors for many small molecules, as well as many pumps and channels.
