$A$ only

Vedclass · Answer

(A) The $Na^+ - K^+$ pump is an active transport mechanism that maintains the resting membrane potential in neurons.$1$. Statement $(A)$ is incorrect because the pump transports $3\, Na^+$ ions $OUTSIDE$ the cell and $2\, K^+$ ions $INSIDE$ the cell.$2$. Statement $(B)$ is correct; it uses $ATP$ to maintain the ionic gradient via active transport.$3$. Statement $(C)$ is correct; it moves ions against their respective concentration gradients (pumping $Na^+$ out where it is already high and $K^+$ in where it is already high).Since only statement $(A)$ is incorrect,the answer is $A$ only.

Regarding the $Na^+ - K^+$ pump:
$(A)$ It transports $3\, Na^+$ ions inside and $2\, K^+$ ions outside.
$(B)$ It maintains the ionic gradient through active transport.
$(C)$ It works against the concentration gradient.
Which of the above statements are incorrect?
