In other words, a diagram of the membrane (like the one below) is just a snapshot of a dynamic process in which phospholipids and proteins are continually sliding past one another. Find the template you need and change it using powerful tools. If they make it to the hydrophobic portion of the membrane, the next lowest area of concentration would likely be the inside of the cell. For a typical human cell, however, proteins account for about 50 percent of the composition by mass, lipids (of all types) account for about 40 percent, and the remaining 10 percent comes from carbohydrates. Cell Protection The Plasma Membrane Reply Key Pdf Step 8. By binding to carrier proteins they won't precipitate or accumulate in specific places and can do their thing in cells where they are supposed to do their thing. Outside the cell, in the surrounding water-based environment, are ions, acids, and alkalis that are toxic to the cell, as well as nutrients that the cell must absorb in order to live and grow. menu.
