Does sodium move by active transport?
Sodium ions are thought to get into a cell by diffusion through special spores in the membrane and are expelled by a form of active transport .
Do sodium ions move to inside of neuron in a nerve impulse?
No. Three sodium ions are pumped out of the neuron by the sodium-potassium pump and two potassium ions enter the cell. This way you maintain a slightly negative charge just inside the cell membrane.
What's the direction sodium ions are pumped?
Sodium ions and potassium ions are pumped in opposite directions. Sodium ions are pumped out of the cell and potassium ions are pumped into the cell.
The sodium potassium pump prevents the accumulation of?
Sodium potassium pump prevents accumulation of K out side of cell and Na inside of cell.
Sodium pumped out of a nerve cell?
Swett
How does sodium ion molecule move into the cell through cell membrane?
Through diffusion.
Process by which ATP is used to move sodium ions out of the cell and potassium ions back into the cell?
Sodium-Potassium pump uses ATP (energy) to pump sodium out of cells and potassium back in.
What is the change of ion pump to move ion across the cell membrane?
Sodium Potassium pump
Does sodium move by active transport?

What is the mechanism in which ATP is used to move sodium out of the cell and potassium into the cell restores the resting membrane voltage and intracellular ionic concentrations?
Repolarization The questioner was looking for the mechanism not the process. The answer is the sodium potassium pump.
Do sodium ions move to inside of neuron in a nerve impulse?
No. Three sodium ions are pumped out of the neuron by the sodium-potassium pump and two potassium ions enter the cell. This way you maintain a slightly negative charge just inside the cell membrane.
What is the process by which ATP is used to move sodium ions out of the cell and potassium ions back into the cell and completely restores the resting conditions of the neuron?
repolarization
What does the Na1 Ka1ATPase transport sodium and potassium into a cell sodium and potassium out of a cell sodium into cell potassium out of cell sodium out of cell potassium in ATP?
NaKATPase transports 3 K ions into the cell and takes only two Na ions out of it.
At the threshold stimulus sodium ions start to move into the cell or out of cell to bring about the membrane depolarization?
For depolarisation to occur as part of an action potential, +40 mV inside the neuron fibre compared to outside the membrane. For summation after a synapse to determine whether the post-synaptic neuron will fire an action potential, the threshold is +20mV inside the neuron compared to the outside.
If a voltaic cell is made with lithium and sodium electrodes what happens at the cathode of the cell?
Solid sodium forms. Sodium is reduced.
What is a brief description of the action of the sodium-potassium pump?
The sodium-potassium pump is a transmembrane protein in a cell membrane. It keeps large concentrations of sodium ions outside the cell, and potassium ions inside the cell. It does this by pumping the sodium ions out, and the potassium ions in.
Chemicals that move in and out of cells by diffusion?
The cell cotains phospholipids ,proteins , and carbohydrates. Carbohydrates can be attached to either the phospholipids or the proteins in the cell membrane. Sometimes carbohydrates (sugars) are attached to cell membrane phospholipids and to cell membrane proteins
