7. Draw relative concentrations of chloride, potassium, sodium, and large an ions in the ICF and ECF. No need for exact numbers, just make sure it's clear which compartment has more of the ion than the other. Circle the ion that contributes most heavily to resting membrane potential in a normal neuron. Then, add the equilibrium potentials (as applicable) of these ions and define what an equilibrium potential is, then add arrows to indicate how each of these ions would move if the rest \( E_{m} \) is \( -100 \mathrm{mV}_{\text {; - }} \) \( 70 \mathrm{mV} \), and \( +70 \mathrm{mV} \). 8. in the margins, draw out the Nernst equation and use it to determine the equilibrium potential of ion \( X \), which is positively charged and has a concentration of \( 50 \mathrm{mM} \) outside of the cell and \( 10 \mathrm{mM} \) inside of the cell; then, draw how this ion would cross the membrane if rest \( E_{M} \) is \( -100 \mathrm{mV},-70 \mathrm{mV} \), and \( +70 \mathrm{mV} \) 9. draw another enlargement box on the membrane of your cell and in this box draw out the cycle of the sodium potassium pump, providing some brief, explanatory bullet points describing the process topic 1 - Cull Paysiongy and rotting mumbrane pocential
