I.E.1. Net forces on K + Question: What is the direction of the chemical force acting on potassium ions at this stage? A. from high to low concentration IMPORTANT POINT: Na ions , Na channels and the voltage across the cell membrane are just distractions. The only information you need is the concentration of potassium and the temperature!! Question: How would you calculate the magnitude of the chemical force acting on potassium ions? (Hint: Notice [] and voltages are the same as in the intermediate state of the 3 beaker overhead from ealrier in the class.) A. The concentrations of potassium are the same and the temperature is the same, so the magnitude of the chemical force should be the same as in the intermediate state from the 3- beaker overhead beaker condition. Question: What is the direction and magnitude of the electrical force acting on potassium, ions at this stage? (Hint: Remember that the magnitude of the electrical "field" force acting on an ion at any time ONLY depends on the voltage difference across the cell
