€‹how do sodium and potassium travel into and out of cells? ​antidiuretic hormone transports potassium and prodiuretic hormone carries sodium. ​specific transport proteins in the blood deliver the minerals to the cell cytoplasm. ​the balance of insulin and glucagon determines the movement of these minerals into and out of cells. ​transport proteins within the cell membrane pick up and release the minerals across the membrane. a negative feedback loop uses blood glucose levels for transfer.​
