Effects Of Solutions On Ion Transport Across Membranes
Abstract
Concentration gradients exist between two different salt molarity solutions on opposite sides of a membrane. Movement of ions across these sides can be achieved by either active or passive diffusion. In our first three experiments we used these concentration gradients to determine the characteristics of selective permeability of an artificial membrane to potassium chloride (KCl), the potential difference across the skin of a frog, Rana pipens, …showed first 75 words of 2178 total…

…showed last 75 words of 2178 total…membrane. The results showed that because the addition of cyanide, which inhibits ATP use, and ouabain, which blocks the Na/K pump all together, decreased the potential difference and current across the membrane, that ATP was very much needed in the functioning of the Na/K pump.
