Answer:
Active transport necessary for the sodium-potassium pump to work because It allows sodium and potassium to move against their concentration gradient.
Step-by-step explanation:
The transport of sodium ions outside the cell and potassium ions inside the cells is called active transport that requires the ATP hydrolysis. ATP provides the energy required for this procedure. This sodium-Potassium pump works to move the ions against their concentration gradient to keep the sodium concentration low inside the cells and potassium concentration high inside the cells.
