Answer:
The correct answer is B) cell membrane pump
Step-by-step explanation:
Na+k+ ATPase pump helps animal cells to maintain Na+/K+ level homeostasis.Na+K+ATPase pump perform this function by active transport.
The sodium potassium pump helps in the movement of both Na+ and K+ ions against their concentration gradient across the plasma membrane.
As a result additional energy is required for the uphill transport of sodium and potassium ions in and out of the cell is derived from the hydrolysis of ATP.
