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.

∙ 11y agoThe sodium/potassium pump uses energy (ATP) because it has to pump sodium ions out of the cell and potassium ions into the cell. This is against the concentration gradient. The difference between the sodium outside and the potassium inside produces an electrical gradient. The outside of the cell is more positive than the inside. This allows a signal or "current" to be transmitted.

What does the Calvin cycle use to produce high enerji sugars?
nadph and atp
If muscle contractions use ATP at or below the maximum rate of ATP generation by mitochondria the muscle fiber will what?
produce lactic acid
What use light to create chemical energy and produce ATP?
Plants use light to create chemical energy and produce ATP. This is done through a complicated process also known as photosynthesis.
Does the mitochondria produce ATP?
Yes,they produce ATP.Aerobic respiration produces ATP.
How does a cellular respiration allow a cell to produce ATP?
Yes is does, the chemical formula for cellular respiration is: C6H12O6 + 6O2 --> 6CO2 + 6H2O + ADP Glucose + Oxygen -> Carbon dioxide + Water + energy(ATP) The cell breaks up the glucose into Energy in the form of ATP which the plant can then use ~element. A definition of 'a fruitless exercise' is to try to find even one cellular process that does not require ATP.
What use ATP to produce sugar?
The energy in glucose (Cellular respiration) is used to produce ATP
Mitochondria produce ATP by?
They produce ATP by oxidizing Glucose. Energy is stored in glucose.
When they use energy what does living things produce?
ATP
The purpose of cellular respiration is to create and use?
produce energy in the form of ATP
What cell uses rich organic compuonds used to produce ATP?
Mitochondria use rich organic compounds, glucose, to produce ATP.
During rapid exercise how do your muscles produce ATP?
Fueled by the metabolism of sugar, the ATP byproducts (ADP) are reconstituted into ATP molecules. Use of ATP energy requires no oxygen - when the ATP is depleted the muscle cells must use cellular respiration to obtain energy and once the muscle is at rest the ATP stores are replenished.
What does the Calvin use to produce high energy?
ATP and NADPH
What energy source does the cell use to work the sodium potassium pump?
ATP
What are three main fates of glucose?
Immediate use to produce ATP molecules,storage for later ATP production,or for use in building other molecules.
