Lecture for Exam 3 Ch. 12—Membrane Transport 6. Explain in detail how the Na+/K+ pump works. - Primary active transporter, because it requires ATP to hydrolyze while it is transporting and both are going opposite of their electrochemical gradients. - Is also an Antiporter, because it has opposite physical directions (K+ going in, Na+ going out.) - Na+/K+ pump: transports 3 Na+ OUT and 2 K+ IN; both against the electrochemical gradient. - Charge difference across the plasma membrane: Na+/K+ pump (+1 net out), - molecules inside, K+ leak channels (always open and allows K+ to leak out.) Inside is more – than the outside = membrane potential. 7. Give 2 important functions of the Na
