Membrane potential (also transmembrane potential or membrane voltage) is the difference in electric potential between the interior and the exterior of a biological cell. With respect to the exterior of the cell, typical values of membrane potential range from â40 mV to â80 mV.
stoichiometric compounds. Stoichiometric Compounds are those in which the number of positive and negative ions are exactly in the ratio indicated by their chemical formulae.

Note that nitrate is more often limiting than phosphate. Redfield ratio or Redfield stoichiometry is the atomic ratio of carbon, nitrogen and phosphorus found in phytoplankton and throughout the deep oceans. This empirically developed stoichiometric ratio was originally found to be C:N:P = 106:16:1 (and has more recently been revised to 117:14:1).
