Title: cell physiology practice problem Post by: BioSubi on Oct 16, 2014 A Mammalian cell (permeable to Na+, K+, Cl-, with the usual distribution of ions) has
the following values for ionic equilibrium potentials: ENa=+60 mV, EK = -80 mV and Ec1 = -85 mV. What is the initial direction of movement of each ion (i.e. from outside to inside or vice versa) if the membrane potential is suddenly shifted (this can be done experimentally by injecting current in the appropriate direction) to (a) -80 mV, (b) -90mV and ("c ' ) +70mV? If this cell has a steady state resting potential of -75 |
