Use the image below. showing change in membrane potential of a neuron. to answer the next two questions. Assume that resting membrane potential is -70 mV and threshold is -55 mV. 0\" Explain what is driving the change in membrane potential at step 6. In your answer. include: A. What type(s) of gated channels are closed at step 6? (1 point) 8. Which ions are moving through the membrane. and are they moving into or out of the cell? (1 point) C. Is the membrane depolarizing. repolarizing. hyperpolarizing. or none of these at step 6? (1 point)
