Membrane permeability iron
WebLeakage of ions (Na +, K +) and phosphorylated metabolites (phosphorylcholine, 2-deoxyglucose 6-phosphate) through membrane lesions in intact cells or in cells modified by ‘pore-forming’ agent has been studied. Leakage from intact cells is induced by protons and by divalent cations such as Cu 2+, Cd 2+ or Zn 2+. WebThe membrane is most permeable to potassium at rest, and this leads to potassium efflux. However, the membrane is also permeable to chloride and sodium, and the flow of these ions keep the resting membrane potential more …
