What cannot pass directly through the phospholipids of the plasma membrane? True or False. Regarding the proteins and cholesterol in the animal plasma membrane some proteins are embedded in the bilayer other proteins are only on one side and the cholesterol is scattered throughout the inner parts of the membrane. Cannot rapidly pass directly through the phospholipids of a plasma membrane and to move rapidly through the membrane they must pass through membrane transport proteins. On the other hand hydrophilic molecules (like water and glucose) and ions (such as sodium ions and hydrogen ions ) cannot pass directly through the phospholipids of the plasma membrane. In a watery aqueous environment such as the ocean or the human body a drop of phospholipids will arrange into a sphere with the heads facing the water and the tails protected on the inside. In the plasma membrane there are two layers of phospholipids. The heads form the outer and inner faces of the membrane … Which of these can RAPIDLY pass directly through the phospholipids of the plasma membrane without the help of a transport protein? The cell membrane . There are som...
