In molluscan neurons, the carrier of inward current during the rising phase of the action potential is usually calcium. This ion has an unusually steep concentration gradient. Given the values below, what is the equilibrium potential for Ca2+ at 20 deg Celsius? (Consider the options carefully.) o = 10-2 M i = 1.7 x 10-7 M o log ——— = 4.77 i i log ——— = -4.77 o
