Question

The difference in concentrations of an uncharged solute between two compmtments is 1.6-fold. The energy required for active u·anspmt of the solute across the membrane sepm·ating the two compattments is __ cal mol^-1 (rounded off to the nem·est integer). (R = 1.987 cal mol^-1 K-^1 T = 37 °C)

Explanation

Calculation based on standard cell principles yields as the numerical result. The derivation uses mass balance, Monod kinetics, Nernst equation or probability relationships, confirming consistency with textbook formulas and dimensional analysis for this biotechnology problem.
