![1. (a) In class thus far, we have focused our membrane transport energetics discussions on
the transfer of K+ ions. Of course, in the cell there are other ions that contribute to the
overall resting membrane potential (Autotal). To estimate the overall resting membrane
potential for the predominant ions present in the cell, we must first calculate the
individual resting membrane potential. Using the Nernst equation discussed in class, and
the values provided below, calculate A for each ion.
