Plasma membrane

Vedclass · Answer

(B) The Donnan equilibrium refers to the behavior of charged particles (ions) near a semi-permeable membrane that fails to distribute evenly across the two sides of the membrane. This phenomenon occurs because one side of the membrane contains charged particles (like proteins or fixed ions) that cannot pass through the membrane, leading to an unequal distribution of diffusible ions. In biological systems, this process primarily takes place at the $Plasma 	ext{ } membrane$ (cell membrane), which acts as the semi-permeable barrier regulating the movement of ions between the cytoplasm and the extracellular environment.

At which surface does the Donnan equilibrium occur?
