Effects of growth rate, cell size, motion, and elemental stoichiometry on nutrient transport kinetics

Relationship between Gmax, cell size, and TRDGmax.
Maximum N:C (at G = Gmax) was assumed as 0.18 gN gC-1.The required value for TRDGmax in Cdiat is less than that for Cprot because diatoms, being more vacuolated with a lower gC (cell L)-1, have a decreased demand for N across a given area of cell plasma-membrane. The absolute maximum value of TRD (TRDmax) is expected to be ca. 0.4 pgN μm-2 d-1; large fast-growing protists approach the limit of TRDGmax = TRDmax.
