A two-stage chemostat system is used for production of secondary metabolite. The volume of each reactor is 0.5 m³; the flow rate of feed is 50 l h^{- 1}. Mycelial growth occurs in the first reactor; the second reactor is used for product synthesis. The concentration of substrate in the feed is 10 gl^-1. Kinetic and yield parameters for the organism are:

Assume that product synthesis is negligible in the first reactor and growth is negligible in the second reactor. Determine substrate concentrations entering the second reactor.

Members of the Poaceae family, which includes all of the cereal crops, use benzoxazinoids, these alkaloids shows;

a) Alkaloids are derived from the tryptophan as constitutively produced defensive secondary metabolites

b) These benzoxazinoids such as DIBOA and its derivative DIMBOA are usually stored in the peroxisome

c) Upon damage, the inactive glycosides are hydrolyzed, generating glucosinolate, which are toxic not only to insect herbivores but also against pathogens

d) DIBOA and DIMBOA perform insecticidal and pesticidal activities

e) It can be inactivated by hydroxylation and N-glycosylation reactions

Which of the following combination is correct about benzoxazinoids alkaloids?
