Describe the Three Roles of the Sodium-Potassium Pump

Question

Examlex · Accepted Answer

The Answer is The Na⁺-K⁺ pump plays three important roles: (1)It establishes Na⁺ and K⁺ concentration gradients across the plasma membrane of all cells;these gradients are critically important in the ability of nerve and muscle cells to generate electrical signals essential to their functioning; (2)It helps regulate cell volume by controlling the concentrations of solutes inside the cell and thus minimizing osmotic effects that would induce swelling or shrinking of the cell; (3)The energy used to run the Na⁺-K⁺ pump also indirectly serves as the energy source for secondary active transport.
