Question

the binding and release of sodium or potassium ions are due to conformational changes in the protein. true or false

Explanation:

In ion channels or transporters (like Na⁺/K⁺ - ATPase), conformational changes in the protein are responsible for binding and releasing sodium (Na⁺) and potassium (K⁺) ions. For example, the Na⁺/K⁺ pump undergoes conformational shifts to move these ions across the cell membrane, binding ions in one conformation and releasing them in another. So the statement is correct.

Answer:

True
