Vedclass · Answer

(C) At normal body temperature,the $Na^+-K^+$ pump (an active transport mechanism) maintains a high concentration of $K^+$ ions inside the $RBC$ compared to the plasma.When blood is stored at a low temperature $(4^{\circ}C)$,the metabolic activity of the $RBC$ membrane is significantly reduced.This low temperature inhibits the $Na^+-K^+$ pump,causing active transport to cease.As a result,$K^+$ ions move down their concentration gradient from the $RBC$ into the plasma,eventually leading to ionic equilibrium.

When whole blood is stored with an anticoagulant at $4^{\circ}C$,the $K^+$ ions move out from the $RBC$ into the plasma. The most likely reason for this is that
