ion pumps การใช้

• Another functionally important ion pump is the sodium-calcium exchanger.
• All ion pumps have some sort of trigger or  gating mechanism.
• He proved the presence of an electrogenic ion pump in plant cells.
• This includes cryopumps, getters, and ion pumps.
• Many chambers containing TSPs also have an ion pump.
• These membranes are flat sheets that form a continuous barrier around all ion pumps.
• Potassium regulates the opening and closing of the stomata by a potassium ion pump.
• The PMCA functions in a similar manner to other p-type ion pumps.
• The balance between potassium and sodium is maintained by ion pumps in the cell membrane.
• The action potential involves mainly the opening and closing of ion channels not ion pumps.
• For these very low pressures, either an ion pump or a getter material is used.
• The current generated by ion pumps is dependent on the ionic species specific to that pump.
• Furthermore, TSPs have been shown to be effective against the regurgitation effects of ion pumps.
• Cytotoxic edema may be caused by the failure of cellular ion pumps, which results from hypoxia.
• Ion pumps influence the action potential only by establishing the relative ratio of intracellular and extracellular ion concentrations.
• In particular, ion pumps play no significant role in the repolarization of the membrane after an action potential.
• However, stroke cuts off the supply of oxygen and glucose which powers the ion pumps maintaining these gradients.
• This electrical polarization results from a complex interplay between protein structures embedded in the membrane called ion pumps and ion channels.
• However, in physiology, due to active ion pumps, the inside and outside of a cell are not in equilibrium.
• The cell uses ion channels, ion pumps, and voltage gated ion channels to generate a negative resting potential within the cell.
