False What is the correct label for "A"? proteins. 5. It waits in its closed position, once again, until it is activated by the binding of its target molecule (outside of the cell). Certain molecules use diffusion to cross the plasma membrane. Independent movement means that when they collide, their motions do not become Unlike channels, which are pores through the membrane, carrier proteins transport solutes across the membrane through a sequence of subtle shape This process is called exocytosis. Enzymes that normally work in alkaline environments in the body can become denatured if the pH becomes too acidic. The sodium-potassium pump moves ions against their concentration gradient, from where they are less concentrated to where they are more concentrated. structural support of the cell Remember that small nonpolar molecules pass most easily through cell membranes. If a molecule wanted to diffuse across the plasma membrane, but wasn't able to make it all the way through, what would happen to it? This does not mean that the two types of molecules do not come into contact with each other.
