Vedclass · Answer

(B) The $Bt$ toxin produced by the bacterium $Bacillus 	ext{ } thuringiensis$ exists as an inactive protoxin in the bacteria.When an insect ingests the inactive protoxin, it enters the insect's gut.The alkaline $pH$ of the insect's gut solubilizes the crystals, converting the inactive protoxin into an active toxin.This active toxin binds to the surface of midgut epithelial cells and creates pores, causing cell swelling and lysis, which eventually leads to the death of the insect.
