3. Why is active transport necessary for the sodium-potassium pump to work? A. The sodium would never leave a cell while potassi
um can move against the gradient B. The potassium would never leave a cell while sodium can move against the gradient C. It allows sodium and potassium to move against their concentration gradient D. All channel movement requires active transport to equalize the cell
Active transport necessary for the sodium-potassium pump to work because It allows sodium and potassium to move against their concentration gradient.
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.
It is necessary to separate oxygenated and deoxygenated blood separate in mammals and birds to maintain their body temperature. Also, if they both are mixed, the blood will get impure and it would be difficult for the heart to supply impure blood. We also can't live with impure blood so we most probably will die.
