enzyme1 (E1) is required to convert reactant B to product C. Enzyme 2 (E2) is required for the reverse reaction (C to B). The activity of E1 is 50 pmol of C created/10^6 cells *s and that of E2 is 40 pmol of B created/10^6 cells*s. What are the direction and overall rate of metabolic flux between B and C?
