The Na+/K+ ATPase pump maintains the sodium electrochemical gradient necessary for the function of which transporter?
Understand the Problem
The question asks which transporter relies on the sodium electrochemical gradient established by the Na+/K+ ATPase pump. This requires understanding the function of the Na+/K+ ATPase pump and how it contributes to secondary active transport.
Answer
Secondary active transporters rely on the sodium electrochemical gradient maintained by the Na+/K+ ATPase pump.
The sodium electrochemical gradient maintained by the Na+/K+ ATPase pump is necessary for secondary active transport, including neurotransmitter reuptake and other transport processes.
Answer for screen readers
The sodium electrochemical gradient maintained by the Na+/K+ ATPase pump is necessary for secondary active transport, including neurotransmitter reuptake and other transport processes.
More Information
The Na+/K+ ATPase pump creates a sodium gradient by pumping sodium ions out of the cell. This gradient then drives the movement of other substances across the membrane through secondary active transport mechanisms.
Tips
It's important to distinguish between primary active transport (like the Na+/K+ pump itself) and secondary active transport, which relies on the gradients established by primary active transport.
