C6H12O6 + a*O2 + b*NH3 --> c*CH1.64O0.52N0.16 + d*CO2 + e*H2O + f*C2H5OH In the aerobic yeast growth process, overflow metabolism can be observed when the sugar feed rate exceeds the oxidizing capacity of the yeast. In this case, part of the substrate is treated anaerobically and the production of biomass is reduced and ethanol is formed. This can also be observed when the respiratory rate RQ goes above one. The chemical composition of this yeast is CH1.64O0.52N0.16 . The yield of ethanol from glucose is 0.14 g g-1 and the yield of biomass from glucose is 0.362 g g-1. Calculate the oxygen demand of the reaction. In this calculation, use the following rounded even values as atomic weights for all calculations:  C=12 g/mol, H=1 g/mol, O=16 g/mol ja N=14 g/mol.  So how many moles of oxygen are needed per mole of glucose?

Inositol hexaphosphate (phytic acid, InsP6) is converted to 5-InsP7 by the action of the enzyme IP6K using adenosine 5'-triphosphate (ATP) as the substrate. What is the byproduct (indicated by ?) in the reaction? 2-O3PO OPO,2- InsPs 2-O3PO 5-InsP7 IP6K OPO,2- 2-O3PO- FOPO32 0- FOPO,2 2-03PO- OPO,2 OPO,2- АТР ? adenosine adenosine 5'-monophosphate adenosine 5'-diphosphate adenine

If 0.1 M glucose-1-phosphate is incubated with phosphoglucomutase, the glucose-1-phosphate is transformed to an isomer. At equilibrium, the concentration of glucose- 1-phosphate is 4.5 x 10'M and that of the isomer is 8.6 x 10 M. Calculate K' and AGo" for this reaction (i.e., in the direction of product formation). (R = 8.314 J/mol K)
