Final answer:
The Goldman equation calculates the resting membrane potential based on ion permeability and concentration inside and outside the cell, but not the concentration of all ion channels in the membrane.
Step-by-step explanation:
The Goldman equation is utilized to determine the resting membrane potential of a cell. It accounts for several factors that influence this potential, including the permeability of the membrane for specific ions, the concentration of an ion inside the cell, and the concentration of an ion outside the cell. However, it does not consider the concentration of all ion channels in the membrane, as the Goldman equation specifically deals with the permeabilities and concentrations of ions rather than the quantity of ion channels.
