Question

Under certain circumstances, potassium ions (K+) in a cell will move across the cell membrane from the inside to the outside. The potential inside the cell is-80.5 mV and the potential outside the cell is zero. What is the change in the electrical potential energy of a single potassium ion as it moves across the membrane? change in potential energy: Does the potential energy of the potassium ions increase, decrease, or remain the same as the ions move from the inside to the outside? D increase O remain the same O decrease
