When a nerve cell (neuron) or muscle cell react, they do so by a process called depolarization. Before depolarization, the inside of the cell is slightly negative and the outside is slightly positive. During depolarization, sodium ions rush into the cell while potassium channels leak out. This reverses the original polarization and now the cell is said to be depolarized. The sodium/potassium pump helps reverse this back to its original polarized state so the cell can react again.

Which statements are not true about the sodium potassium pump?
The sodium-potassium pump moves sodium ions out of the cell and potassium ions into the cell. The pump functions using energy from ATP hydrolysis. The pump maintains the chemical and electrical gradients of sodium and potassium ions across the cell membrane. The pump is found only in prokaryotic cells and not in eukaryotic cells.
The sodium potassium pump prevents the accumulation of?
The sodium-potassium pump prevents the accumulation of sodium ions inside the cell and helps maintain the proper balance of sodium and potassium ions across the cell membrane. This pump actively transports three sodium ions out of the cell for every two potassium ions it transports into the cell, utilizing ATP energy in the process. Disruption of this pump can lead to cellular and physiological imbalances.
What provides energy to run sodium potassium pump?
The energy to run the sodium-potassium pump is provided by ATP (adenosine triphosphate) hydrolysis. When ATP is broken down into ADP (adenosine diphosphate) and inorganic phosphate, energy is released and used to transport sodium ions out of the cell and potassium ions into the cell through the pump.
What molecule powers the sodium potassium pump?
The sodium-potassium pump is powered by ATP (adenosine triphosphate). ATP provides the energy needed for the pump to actively transport three sodium ions out of the cell and two potassium ions into the cell against their respective concentration gradients.
Where sodium potassium pump present?
The most likely place you're going to find a sodium potassium pump would be in the muscle cell membrane. The sodium potassium pump reverses the electronegative potential once the cell has depolarized. In other words, it primes the muscle cell to be able to contract again.
Is the sodium potassium pump a protein?
Yes, the sodium-potassium pump is a protein.
What pumps excess water from the cell helping to maintain homeostasis?
The sodium-potassium pump is responsible for pumping excess water out of the cell to help maintain homeostasis. This pump works by actively transporting sodium ions out of the cell and potassium ions into the cell, creating a concentration gradient that helps regulate water balance.
Process by which ATP is used to move sodium ions out of the cell and potassium ions back into the cell?
This process is called the sodium-potassium pump. It uses ATP to pump sodium ions out of the cell against their concentration gradient and pump potassium ions back into the cell against their concentration gradient. This mechanism helps maintain the appropriate balance of sodium and potassium ions inside and outside the cell, which is crucial for cellular functions such as nerve transmission and muscle contraction.
What is the sodium potassium pump?
the sodium-potassium pump is one of the most important carrier proteins in the animal cell.
Is the sodium potassium pump a carrier protein?
Yes, the sodium-potassium pump is a type of carrier protein that helps transport sodium and potassium ions across the cell membrane.
What is the active transport mechanism by which cells pump sodium and potassium ions against the concentration gradient.?
sodium-potassium pump
Which statements are not true about the sodium potassium pump?
The sodium-potassium pump moves sodium ions out of the cell and potassium ions into the cell. The pump functions using energy from ATP hydrolysis. The pump maintains the chemical and electrical gradients of sodium and potassium ions across the cell membrane. The pump is found only in prokaryotic cells and not in eukaryotic cells.
Which ions are exchanged in a sodium potassium pump?
3 sodium ions for 2 potassium ions.
What moves in the sodium potassium pump?
In the sodium-potassium pump, three sodium ions are pumped out of the cell while two potassium ions are pumped into the cell. This movement is powered by ATP, which is hydrolyzed to provide the energy needed for the pump to function.
How many ATP is used in a sodium potassium pump?
The sodium-potassium pump uses one molecule of ATP to transport three sodium ions out of the cell and two potassium ions into the cell.
Does facilitated transport have a sodium potassium pump?
The sodium potassium pump requires ATP - i.e. it is involved in active transport, not facilitated transport.
The sodium potassium pump prevents the accumulation of?
The sodium-potassium pump prevents the accumulation of sodium ions inside the cell and helps maintain the proper balance of sodium and potassium ions across the cell membrane. This pump actively transports three sodium ions out of the cell for every two potassium ions it transports into the cell, utilizing ATP energy in the process.
