What structure uses ATP to move ions to create a resting potential in a neuron cell membrane?
|
|
Voltage-gated channel
|
|
|
Magnesium-Calcium pump
|
|
|
Ligand-gated channel
|
|
|
Sodium-Potassium pump
|
Explanation:
Detailed explanation-1: -Resting membrane potentials are maintained by two different types of ion channels: the sodium-potassium pump and the sodium and potassium leak channels.
Detailed explanation-2: -The sodium-potassium pump system moves sodium and potassium ions against large concentration gradients. It moves two potassium ions into the cell where potassium levels are high, and pumps three sodium ions out of the cell and into the extracellular fluid.
