C. roseus cells immobilized in Ca-alginate beads of diameter 0.5 mm are used for production of indole alkaloids (IA) in a fluidized-bed bioreactor. The rate limiting nutrient is glucose and no intraparticle diffusion limitations exist. Use the following data: Flow rate of the feed: Q = 1 l/h, Glucose in the feed: So = 30 g/l, Plant Cell Concentration: X = 6 g/l reac. The rate constant for IA formation: k = 5 d-1 (g/l)^-1 Ks = 0.4 g/l, Column diameter: Do = 0.15 m. Growth is negligible and Monod kinetics is valid. For 95% glucose conversion determine volume.

 a) Chalcone synthase catalyzes the conversion of p-Coumaroyl-CoA into Chalcones

 b) Substrate for Chalcone synthase is chalcone

 c) CHS activity increased by environmental factors, such as light, and fungal infection

 d) Chalcone synthase is enzyme in flavonoid biosynthesis catalyzes stepwise condensation into p-Coumaric acid by using Malonyl-CoA molecules

 Which of the following combinations of above statement is true?
