The Na+/K+ pump is an excellent example of Primary Active Transport.

Question

BlackTom AI · Accepted Answer

The question presents a statement about the Na+/K+ pump in the context of transport mechanisms. 
Option: True. 
To evaluate this, consider what primary active transport entails: movement of substances against their electrochemical gradients that requires direct input of energy from ATP hydrolysis. 
The Na+/K+ pump fits this definition precisely, as it uses one molecule of ATP to drive the conformational changes of the pump, enabling the export of three Na+ ions and the import of two K+ ions against their respective gradients. 
This pump is a classic example of a P-type ATPase, in which phosphorylation during the cycle is central to its mechanism, illustrating direct coupling of ATP hydrolysis to ion transport. 
Because energy for transport comes directly from ATP and the movement is against the gradient, this is a textbook case of primary active transport. 
In contrast, if one were considering secondary active transport, the pump would rely on an ion gradient established by primary transporters rather than directly consuming ATP at the moment of transport, which is not the case here. 
Therefore, the statement accurately describes the Na+/K+ pump as a primary active transporter, reflecting both energy source and transport mechanism.
