When sodium ions (Na+) are pumped out of the cell, typically by the sodium-potassium pump (Na+/K+ ATPase), ATP is hydrolyzed to provide the necessary energy for this active transport process. Specifically, one molecule of ATP is consumed to move three Na+ ions out of the cell while bringing in two potassium ions (K+) in. This process helps maintain the cell's electrochemical gradient, which is crucial for various cellular functions, including nerve impulse transmission and muscle contraction. As a result, the overall ATP levels decrease in the cell as energy is utilized for maintaining ion balance.

When are electrons and H ions used in cell respiration?
Electrons and H+ ions are used in cell respiration during the electron transport chain to generate ATP through oxidative phosphorylation. Electrons are passed along a series of protein complexes, pumping H+ ions across the inner mitochondrial membrane, creating a proton gradient that drives ATP synthesis by ATP synthase. This process is critical for generating the majority of ATP in cells.
Does relaxation require ATP?
No, relaxation does not require ATP. ATP is primarily used for muscle contraction. Relaxation occurs when calcium ions are actively pumped out of the muscle cell, which does not require ATP.
Does the sodium-potassium pump use ATP or produce ATP?
Yes. It is open to the cytoplasm and has a high affinity and three binding sites for sodium ions which dock in the trans-member protein pump. An ATP phosphorylates the pump and a conformational change causes the pump to expose the sodium ions to the extra cellular space due to low affinity for sodium ions in this conformation. This conformation has high affinity for potassium ions and two ions dock on the protein pump. The phosphate group that was on the pump disassociates and a conformational change exposes the potassium ions to the cytoplasm where they, now having low affinity for the pump, fall into the cytoplasm. The cycle repeats. and the electrical balance, slight positivity on the outside of the cell and slight negativity on the inside of the cell, is maintained.
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.
How can the cell move sodium out of the cell?
Cells can move sodium out of the cell using a protein called the sodium-potassium pump. This pump actively transports sodium ions out of the cell while bringing potassium ions into the cell, maintaining the proper balance of ions inside and outside the cell. This process requires energy in the form of ATP.

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.
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
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 happens in the sodium-potassium pump during the process of active transport"?
During active transport in the sodium-potassium pump, three sodium ions are pumped out of the cell while two potassium ions are pumped into the cell against their concentration gradients, using energy from ATP.
Does relaxation require ATP?
No, relaxation does not require ATP. ATP is primarily used for muscle contraction. Relaxation occurs when calcium ions are actively pumped out of the muscle cell, which does not require ATP.
What happens to ATP when a muscle cell demands energy to contract?
ATP is hydrolyzed and turned into ADP
Which substances are transported across the cell membrane by ATP requiring transport pumps?
Substances such as ions like sodium, potassium, calcium, and hydrogen are transported across the cell membrane by ATP requiring transport pumps. These pumps consume ATP energy to move ions against their concentration gradient.
What is ATP and what role is it in the cell?
a large protein that uses energy from H+ ions to bind ADP and a phosphate group together to produce ATP.
What is ATP and is its role in the cell?
a large protein that uses energy from H+ ions to bind ADP and a phosphate group together to produce ATP.
What is a carrier protein that used ATP to actively transport sodium ions out of a cell and potassium ions into the cell?
That would be the Sodium-Potassium pump. Pretty creative name eh?
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.
