Under certain circumstances, potassium ions K + move across the 8.0-nm-thick cell membrane from the inside to the outside. The potential inside the cell is -55.0 mV, and the potential outside is zero. Assume that a potassium ion carries a charge of 1.602 x 10 -19 C. 1) What is the change in the electrical potential energy of the potassium ions as they move across the membrane? (Express your answer to three significant figures.) X10-20 J Submit 2) Does their potential energy increase or decrease as they move from the inside to the outside? Oincrease decrease Submit
