Vedclass · Answer

(D) $Bt$ toxin is not toxic to human beings because the conversion of the inactive pro-$Bt$ toxin to the active $Bt$ toxin state takes place only in highly alkaline conditions.In the gut of the target insect,the alkaline $pH$ solubilizes the crystals,allowing the toxin to become active.In contrast,the human stomach has an acidic $pH$,which does not facilitate this conversion,thus rendering the toxin harmless to humans.
