Acetobacter aceti converts alcohol to acetic acid according to the schiometric relation

In a vigorously agitated and aerated reactor containing 20 g/l ethanol, the organism produces 16g/l acetic acid and 2g/l was the residual ethanol concentration what are the theoretical and observed yields of acetic acid expressed in g/g ethanol

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?
