In biological systems, enzymes are used to accelerate the rates of certain biological reactions. Glucoamylase is an enzyme that aids in the conversion of starch to glucose (a sugar that cells use for energy). Experiments show that 1 μg mol of glucoamylase in a 4% starch solution results in a production rate of glucose of 0.6 μg mol/(mL)(min). Determine the production rate of glucose for this system in units of lb mol/(ft3)(day). A. 0.0015 lb mol/(ft3)(day) B. 0.0315 lb mol/(ft3)(day) C. 0.0539 lb mol/(ft3)(day) D. 0.3569 lb mol/(ft3)(day)
