Select the correct answer from each drop-down menu. 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 .

1) By breaking of ATP to ADP

2) The sodium and potassium ions are transported using active transport process!

Explanation:

In cell, the movement of ions across the membrane at the expense of energy is known as Active Transport. The energy is used in the form of ATP(Adenosine Triphosphate) that gets converted to ADP(Adenosine diphosphate) during transport. It takes the ions from high concentration to low concentration. ADP contains one less phosphate group that ATP, as their name indicates and plays a prime role in the flow of energy to the cells.

the answer is:

carbon dioxide
