Which of the following is comparable to a negative feedback cycle? opening of voltage-gated Na" channels in response to a depolarizing graded potential movement of K* through leak channels opening of voltage-gated K* channels in response to a depolarizing graded potential operation of the Na -K ATPase at rest opening of voltage-gated Ca- channels in response to an action potential arriving at the axon terminal

Which of the following is FALSE about action potentials? At resting potential, there are more potassium channels open and most sodium channels are closed. Depolarization is due to the flow of Na+ out of the axon via voltage-gated Na+ channels. Hyperpolarization is due to continued loss of K+ from the axon. During repolarization, K+ flows out of the axon along its concentration gradient. Resting membrane potential is primarily established by the Na+/K+ pump.

At rest, all gated Na+ and K+ channels are closed.Local currents __________ the axon, and voltage-gated Na+ channels __________, allowing Na+ ions to enter the cell. As the depolarization reaches threshold, this behavior becomes self-generating (as more Na+ rushes into the cell, the current causes more/neighboring voltage gated Na+ ion channels to open… positive feedback).
