Sodium ions are pumped out of a red blood cell?
passive 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.
When the ions are moving across the membrane during the depolarization and repolarization phases of an action potential they are moving by?
Depends on what stage you are talking about. Stimulus of sodium ions from dendrites of other neurons must reach a threshold. Once that threshold is reached, sodium ions quickly diffuse into the neuron via facilitative diffusion, depolarizing the neuron. Upon this occurring, sodium channels close and potassium ions are pumped out of the neuron via active transport, leading to repolarization of the neuron.
Is NaHCO3 a metal?
No. Sodium bicarbonate is an ionic compound consisting of sodium ions, hydrogen ions and carbonate ions. While sodium is a metal, the compound in whole is not.
What are two ions that are needed for nerve transmission?
Not minerals, it is ions. Calcium ions and sodium ions.
What ions are pumped in and out of cell through the sodium potassium pump?
3 sodium ions go out and 2 potassium ions go in

The sodium-potassium pump uses no energy to function?
Using energy supplied by ATP, sodium ions are constantly pumped out of the nerve cell while at the same time potassium ions are pumped into the cell. This is termed 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.
How many potassium ions does the sodium-potassium pump move into a cell if it moves six sodium ions out of the cell?
I think you're looking for three ... over the long run. But the trick is that K+ doesn't need to be pumped in. Membrane proteins act as variable sized pore in the membrane (channels) and the potassium flows in under electrostatic forces ... all the work is done pumping the Na+ out.
What does the proximal do?
Sodium brings ions, organic molecules, vitamins and water into the epithelial cells, which is then pumped by Na/K ATPase into the interstitial space, which then flows into the blood.
Which ions are exchanged in a sodium potassium pump?
3 sodium ions for 2 potassium ions.

How many sodium ions there in 85g of sodium oxide Na2O?
The number of sodium ions is 16,518.10e23.
Can liquid electrolyte which does not have sodium molecules conduct sodium ions?
no liquid electrolyte which does not have sodium molecules conduct sodium ions because when liquid electrolyte does not have sodium molecules . so there r no sodium molecules and hence there r no any sodium ions. so how can liquid electrolyte conduct sodium ions.
Sodium chloride is formed from ions and chloride?
Not quite right. Sodium chloride is formed from sodium ions (Na+) and chloride ions (Cl-)
