Introduction Molecules are constantly in motion due to thermal energy. Therefore‚ the molecules will move around and bump into each other. Because of this‚ molecules tend to spread out evenly into available space in a process called diffusion. Diffusion is the random process of molecules moving from areas of high concentration to low concentration‚ thus requiring no energy. Many of the substances that enter or leave the cell do so through diffusion. Osmosis‚ a type of diffusion‚ is the movement

Resting potential is created by a transport protein called the sodium-potassium pump. Resting potential occurs when ions are distributed unequally on the inside and outside of cells‚ and when cell membranes are selectively permeable to different ions. K+ is particularly important for the resting potential. The membrane is highly permeable to K+. In addition‚ the inside of the cell has a high concentration of K+ and the outside of the cell has a low concentration of K+. K+ will naturally diffuse

Resting membrane potentials Definition: Large nerve fibers when not transmitting nerve signals is about 90 millivolt. That is‚ the potential inside the fiber is 90 millivolts more negative than the potential in the extracellular fluid on the outside of the fiber. The Na+-k+ pump also causes large concentration gradients for sodium and potassium across the resting nerve membrane. These gradients are the following: Sodium ( outside): 142 mEq/L Sodium ( inside): 14 mEq/L Potassium ( outside):
