Sodium and potassium ions are essential for muscle contractions of the heart. the ions are transported using a pump, which obtains energy by the breaking of . this action requires the expense of energy. so, sodium and potassium ions are transported using . nextreset

The ions are transported with the help of sodium-potassium pump that obtains energy by the breaking of ATP. This form of transportation is known as active transport.

Explanation:

In the active form of transportation, energy is needed to mediate the ions of sodium and potassium against the concentration gradient. There are two forms of active transport, that is, primary active transport and secondary active transport. In primary active transport energy in the form of ATP is used directly to conduct ions across a membrane, and in secondary active transport, no direct coupling of ATP takes place, however, in this energy is obtained due to the pumping of protons across the membrane.
