The anomalous rectification and cation selectivity of the membrane of a starfish egg cell.

SummaryThe cation selectivity and its relation to the inward-going rectification of the immature egg cell membrane of a starfish,Nordora punctiformis, were studied and the following results were obtained. (1) When the external saline contains usual ion species the cell membrane at rest is predominantly permeable to K ions. The K chord conductancegk depends on the electrochemical potential of K ions, ΔV=V−EK′ and the external K concentration [K+]o by
