b
1 sodium ion out, 1 potassium ion in
QuestionChoice
This is correct. The sodium-potassium pump is a transmembrane ATPase pump. In each cycle, it actively moves 3 sodium ions out of the cell and 2 potassium ions into the cell. This is a fundamental process in maintaining cell function and regulating the electrochemical gradients across the cell membrane.

A 55 year old female is admitted to the general medical ward with severe dehydration and electrolyte imbalances due to prolonged vomiting and diarrhoea.

The sodium-potassium pump is a critical ion transporter in maintaining cell function.

Which of the following describes the movement of sodium and potassium ions for each cycle of the sodium-potassium pump?
a
