Summary Introduction
To write:
The three important roles of the sodium-potassium pump.
Introduction:
The sodium-potassium pump performs the process of moving sodium and potassium ions through the membrane of the cell. It is an active mode of transportation, that is, requires energy in order to pass the molecules. In the process, hydrolysis of ATP (adenosine triphosphate) is done to provide the energy that performs an essential role in the process.

- What is the Contribution of Ion Pumps?arrow_forwardDescribe the contribution of each of the following to establishing and maintaining membrane potential: (a) the Na+K+ pump, (b) passive movement of K+ across the membrane, (c) passive movement of Na+ across the membrane, and (d) the large intracellular anions.arrow_forwardThe rate at which the Na+K+ pump operates is not constant but is controlled by a combined effect of changes in ICF Na+ concentration and ECF K+ concentration. Do you think the changes in both ICF Na+ and ECF K+ concentration following a series of action potentials in a neuron would accelerate, slow down, or have no effect on the Na+K+ pumps in this cell?arrow_forward
