Cyanogenic Glycosides and Glucosinolates are nitrogen containing secondary metabolites in plants. Following are some statements regarding the action of Cyanogenic Glycosides and Glucosinolates;

a) Cyanogenic Glycosides release the poison hydrogen cyanide by the action of enzyme known as Hydroxynitrile lyase

b) Release of the mustard-smelling volatiles from glucosinolates is catalyzed by a hydrolytic enzyme, called a thioglucosidase or myrosinase

c) substerate for Glycosidase is Cyanogenic glycoside and Thioglucosidase is Aglycone

d) Like cyanogenic glycosides, glucosinolates are stored in the intact plant separately from the enzymes that hydrolyze them, and they are brought into contact with these enzymes only when the plant is crushed

Which of the following combinations of above statement is true?

E. coli was continuously cultured in a continuous stirred tank fermenter with a working volume of 1.0 I by chemostat. A medium containing 4.0 g1^-1 of glucose as a carbon source was fed to the fermenter at a constant flow rate of 0.5 I h^-1, and the glucose concentration in the output stream was 0.20 g1^-1, The cell yield with respect to glucose YxS was 0.42 g dry cells per gram glucose. Determine the cell concentration in the output stream
