Both water and glucose share an —OH that can serve as a substrate for a reaction with the terminal phosphate of ATP catalyzed by hexokinase.  Glucose, however, is about a million times more reactive as a substrate than water.  The best explanation is that:

The growth of a microorganism on glucose is described by the Monod model (µmax = 0.7 h¹ and Ks = 0.1 g L¹). If the initial biomass concentration in the batch fermenter is 0.1 g L¹, the minimum time required to triple the biomass concentration would be
