First, the pump is open to the inside of the cell. It naturally "likes"* the sodium (and "dislikes" potassium) so it attracts sodium ions. An ATP molecule then gives one of its phosphate groups to the pump, causing the pump to change. That ATP molecule is now and ADP molecule. With the addition of the phosphate group, the pump now "dislikes" sodium and "likes" potassium. So it closes and reopens to the outside of the cell, releasing the sodium. It attracts potassium ions. Next, the pump gives its phosphate group back to the ADP molecule. That ADP molecule is now an ATP molecule again. Without the phosphate group, the pump "likes" sodium and "dislikes" potassium again. So it closes and reopens to the inside of the cell, releasing the potassium into the cell. The pump now attracts sodium ions. The cycle starts again. For every three sodium ions released, two potassium ions enter.
*"Likes" or "dislikes" refer the pump having a higher or lower affinity (attraction) for one of the two elements.
To answer your question, the ATP molecule is the source and the receiver of the phosphate group, which changes whether the pump "likes" sodium or potassium.
ATP provides the energy necessary for the sodium-potassium pump to function by transferring phosphate groups to transport sodium out and potassium into the cell against their concentration gradients. This ATP-dependent process helps maintain the cell's resting membrane potential and is crucial for various cellular functions, including nerve signal transmission and muscle contraction.

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.
What provides the energy to drive the sodium potassium pump?
The energy for the sodium-potassium pump comes from ATP hydrolysis, where ATP is broken down into ADP and inorganic phosphate. This process helps maintain the concentration gradients of sodium and potassium ions across the cell membrane.
What is the energy needed to power the the sodium-potassium pump is provided by?
The energy needed to power the sodium-potassium pump is provided by adenosine triphosphate (ATP) molecules. These ATP molecules are broken down to release energy that drives the pump's mechanism for transporting sodium and potassium ions across the cell membrane.
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.
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.
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 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.
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.
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.
Which molecule is directly required for operation of the sodium-potassium pump?
ATP (adenosine triphosphate) is the molecule directly required for the operation of the sodium-potassium pump. ATP provides the energy needed to transport sodium ions out of the cell and potassium ions into the cell against their concentration gradients.
What is the role of ATP in sodium potassium pump?
transport across the membrane
What provides the energy to drive the sodium potassium pump?

The energy needed to power the sodium-potassium pump is provided by adenosine triphosphate (ATP) molecules. These ATP molecules are broken down to release energy that drives the pump's mechanism for transporting sodium and potassium ions across the cell membrane.
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.
What energy is used in the sodium equals potassium pump?
The sodium-potassium pump in a cell's membrane is a form of active transportation that uses ATP (adenosine triphosphate) for energy.
What provides energy that drives the sodium-potassim pump?
The energy for the sodium-potassium pump is derived from the hydrolysis of ATP molecules. ATP releases energy when its phosphate group is cleaved, providing the necessary energy to move sodium ions out and potassium ions into the cell through the pump.
