Potassium absorption mechanism
Web14 Apr 2024 · The mechanism of ion transportation in PEs transpires within the amorphous zone via the polymer chain’s segmental motion as well as ion hopping through the polymer chain. Therefore, the incorporation of salt into a polymer matrix is believed to increase ion permeability as well as ion transportation [ 26 ]. WebSodium/potassium ATPase, a sodium pump (active transporter) located on the opposite side of the epithelial cell that takes care of this by moving three sodium ions out of the cell for reabsorption into the bloodstream, and …
