In hereditary spherocytosis, the erythrocytes become trapped in the splenic cords and run out of ATP to pump out excessive ions.What is this ion?

Question

Quizplus · Accepted Answer

In hereditary spherocytosis, erythrocytes have a defect in their membrane proteins, leading to a loss of membrane surface area and a spherical shape. These cells have increased permeability to sodium ions (Na+), which leads to an influx of Na+ that the cell must actively pump out to maintain homeostasis. When ATP is depleted, the Na+ cannot be effectively pumped out, leading to cell swelling and hemolysis.
