Transporting Salt Without Water Involves

Question

Transporting salt without water involves A) a Na⁺-activated Cl^- channel. B) Na⁺ build up inside the cell. C) Na⁺/K⁺ATPase. D) a Cl^--activated Na⁺ channel. E) a NaCl channel.

Accepted Answer

The correct answer involves the Na+/K+ ATPase, which is crucial for transporting sodium (Na+) and potassium (K+) ions across cell membranes, a process that does not directly involve water transport. This mechanism is essential for maintaining cellular ion gradients, which are critical for various cellular functions, including nerve impulse transmission and muscle contraction.
