Suppose that certain neurons of a newly discovered organism were permeable to bo

Question

Suppose that certain neurons of a newly discovered organism were permeable to both CI and K ions but no other ions at rest, and that the resting membrane potential were -75 mV. Suppose also that the the intra-and extracellular concentrations of both ions are as indicated below [Intracellular [Extracellular] C 4 mM K+ 25 mM 100 mM 110 mM Based on this information, what reasonable conclusion can you draw about the relative permeabilities of K+ and ClI ions in these neurons at rest? a. a The membrane is more permeable to chloride ions than to potassium ions at rest. ?? b. The membrane is more permeable to potassium ions than to chloride ions at rest. .At rest, the membrane potential of these neurons lies closer to the potassium equilibrium potential (EK) than it does to the chloride equilibrium potential (EC) d. Both a and c eBoth b and c
