An enzyme-catalyzed reaction was carried out with the substrate concentration initially a thousand times greater than the Km for that substrate. After 9 minutes, 1% of the substrate had been converted to product, and the amount of product formed in the reaction mixture was 12 micromol. If, in a separate experiment, one-third as much enzyme and twice as much substrate had been combined, how long would it take for the same amount (12 micromol) of product to be formed?

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?
