, Insulin transports potassium from
the blood to the cell along with
glucose. Insulin contributes to the
regulation of plasma potassium
levels by stimulating the Na+, K+-
ATPase pump, thereby promoting
1. How is insulin the movement of potassium into
used to treat liver and muscle cells simultaneously
hyperkalemia? with glucose transport after eating.
The intracellular movement of
potassium prevents an acute
hyperkalemia related to food intake.
Insulin also can be used to treat
hyperkalemia.

Hyperaldosteron Hyperaldosteronism promotes (1)
ism causes which increased renal sodium and water
fluid and reabsorption with corresponding
electrolyte hypervolemia and hypertension and
imbalances? (2) renal excretion of potassium.
