Na/K pump: concentrations of Na vs. K on inside/outside of cell, pump action, number of molecules moved
HIKIN’: There is a HIgh K concentration INside the cell. From this can deduce that the Na/K pump pumps K into cell and Na out of cell. Alternatively: When I was learning this pump (circa 1992), a band that was “in” was Kris Kross, and a band that was “out” was “Sha Na Na Na”: So pump moves K K (2 K) in and Na Na Na (3 Na) out. Sadly, as infectious as their debut album was, Kris Kross can really no longer be classed as “in”.
