`Na^+` - `K^+` pump is found in membranes of many cells like nerve cells. It works against electrochemical gradient and involves an integral protein ATPase. At the cost of one ATP, ionic gradient across the resting member is maintained by `Na^+` - `K^+` pump by transporting

Read the following statements, A.)Action potential propagates across the neuronal membrane B) Repolarisation decreases the responsiveness of neuronal membrane to further stimulus C) At resting stage, neuronal membrane is negatively charged on the inside and positively charged on the outside. D) For every 2 Na^+ ions which are transported inside the cell, Na^+ - K^+ pump transports 3K^+ ions to outside,Choose the option which includes correct statements only,

[A]: Active transport results in solute movement against a concentration gradient. [R]: Active transport of Na^+ and K^+ is energized by ATP.

[A] : Active transport results in solute movement against a concentration gradient . [R] : Acitve transport of Na^(+) , K^(+) is energized by ATP .

A : The imbalance in the concentration of Na^(+), K^(+) and proteins generates the resting potential. R : To maintain the unequal distribution of Na^(+) and K^(+) , the neurons use pumps .

[A] : Most of the solutes in ECF and cytoplasm are electrolytes, i.e., electrically charged par- ticles or ions. Maintenance of an equilibrium between intracellular fluid and ECF is vitally essential for all cells. [R]: This osmotic equilibrium is maintained by sodium and potassium pump of the cells. It operates with the help of a Na^+, K^+ ATP as enzyme located in the cell membrane.
