Vedclass · Answer

(D) $Bacillus$ $thuringiensis$ $(Bt)$ produces insecticidal crystalline proteins called $Cry$ proteins in an inactive protoxin form.These crystals remain inactive in the bacterium because the $pH$ of the bacterial cytoplasm is neutral.When an insect ingests the $Bt$ crystals,the alkaline $pH$ of the insect's mid-gut solubilizes the crystals and activates the toxin.The activated toxin then binds to the surface of mid-gut epithelial cells,creating pores that cause cell swelling and lysis,eventually leading to the death of the insect.
