  10. Action Potential • At which labeled point on the action potential is the K+ closest to electrochemical equilibrium? • 1 • 2 • 3 • 4 • 5 Na+ equilibrium potential 3 +35 mV 0mV 2 4 1 -70mV 5 K+ equilibrium potential

  11. Action Potential • What process is responsible for the change in membrane potential that occurs between point 1 and point 3? • Movement of Na+ into the cell • Movement of Na+ out of the cell • Movement of K+ into the cell • Movement of K+ out of the cell • Activation of the NA+-K+ pump • Inhibition of the NA+-K+ pump Na+ equilibrium potential 3 +35 mV 0mV 2 4 1 -70mV 5 K+ equilibrium potential

  12. Action Potential • What process is responsible for the change in membrane potential that occurs between point 3 and point 4? • Movement of Na+ into the cell • Movement of Na+ out of the cell • Movement of K+ into the cell • Movement of K+ out of the cell • Activation of the NA+-K+ pump • Inhibition of the NA+-K+ pump Na+ equilibrium potential 3 +35 mV 0mV 2 4 1 -70mV 5 K+ equilibrium potential
