Depolarization and repolarization changes that occur during the action potential are produced by ____________(a) Negative feedback loops(b) Carrier mediated transport(c) Simple diffusion of ions down their concentration gradient(d) Active transport pumps along the neuron membrane |
Answer» The correct option is (d) Active transport pumps along the neuron membrane Easy explanation: Na^+ channels open at the beginning of action potential and moves into the axon causing depolarization, when K^+ channels open repolarization takes place and moves out of the axon. |
