Describe how the sodium-potassium pump works

WebFeb 24, 2012 · Describes the sodium-potassium pump. Discusses an example of active transport in which membrane protein moves sodium and potassium ions against large concentration gradients. WebSo the difference between a sodium potassium pump and an antiporter is that the sodium potassium pump uses energy directly from an ATP molecule while an antiport uses the energy of a electro-chemical gradient (created by a sodium potassium pump) to move other particles against their gradient.

WebSodium-potassium pump - definition also known as the Na+/K+ pump or Na+/K+-ATPase, this is a protein pump found in the cell membrane of neurons (and other animal cells). It acts to transport sodium and potassium ions across the cell membrane in a ratio of 3 sodium ions out for every 2 potassium ions brought in. WebFigure 5.19 The sodium-potassium pump is an example of primary active transport that moves ions, sodium and potassium ions in this instance, across a membrane against their concentration gradients. The energy is provided by the hydrolysis of ATP. Three sodium ions are moved out of the cell for every 2 potassium ions that are brought into the cell. WebHow a sodium potassium pump can maintain a voltage gradient across a cell or neuron's membrane. The sodium-potassium pump goes through cycles of shape changes to help maintain a negative membrane potential. In each cycle, three sodium ions exit the cell, while two potassium ions enter the cell. the pilot classified ads
