C_L, mean luminal concentration of glucose; J_s, flux of solvent (from Table 2A); J_SC, trans-cellular flux of glucose (J_SC = 48C_L/(C_L+ 7)); C_a, subjunctional glucose concentration in the intercellular channels (from Table 2A); C_cell, glucose concentration in the apical cytosol (from eqn (13)).
