#SCPH05 I Biotechnology

  1. can never occur in a cell.

  2. can occur in a cell only if it is coupled to another reaction for which DG'°is positive.

  3. can occur only in a cell in which NADH is converted to NAD+ by electron transport.

  4. may occur in cells at some concentrations of substrate and product.

#SCPH05 I Biotechnology

Hybridoma cells immobilized on surfaces of Sephadex beads are used in a packed column for production of monoclonoal antibodies (Mab). Hybridoma concentration is approximately X = 5 g/l in the bed. The flow rate of the synthetic medium and glucose concentration are Q = 2 l/h and S0 = 40 g/l, respectively. The rate constant for Mab formation is k = 1 gX/l-d. Assume that there are no diffusion limitations and glucose is the rate limiting nutrient.  Determine the volume of the packed bed for 95% glucose conversion. Bed diameter is D0 = 0.2 m. Neglect the growth of the hybridomas and assume first order kinetics.
