Final answer:
The Na+/K+-ATPase pump is not a ligand-gated ion channel. It is an active transport pump that uses ATP to transport Na+ out of the cell and K+ into the cell, maintaining concentration gradients. It is crucial for various cellular processes.
Step-by-step explanation:
The Na+/K+-ATPase pump is not a ligand-gated ion channel. It is an example of an active transport pump that uses ATP to transport sodium ions (Na+) out of the cell and potassium ions (K+) into the cell. This pump is important for maintaining the concentrations of Na+ and K+ inside and outside the cell, creating a concentration gradient. The Na+/K+-ATPase pump helps establish the resting potential and is crucial for various cellular processes.
