Part A The ion flow rate through an individual potassium ion leak channel in a skeletal muscle cell is about 2x 10° ions/s. This flow rate occurs because the Nernst potential for K+ (VKt = -98 mV) is not What is the conductance in pS of a potassium leak channel? Nernst equal to the membrane potential (Vmem = -90 mV), so the ion concentrations are not in equilibrium. The current through the channel is well modeled as I= G(Vmen –VK). In other words, the ion Express your answer in picosiemens. Nernst flow is driven by the difference between the Nernst potential and the membrane potential. pS
