Vedclass · Answer

(D) The $Bt$ toxin produced by the bacterium $Bacillus$ $thuringiensis$ is ingested by the insect larvae. In the alkaline environment of the insect's $midgut$, the inactive protoxin is converted into its active form. The activated toxin binds to the surface of the epithelial cells of the $midgut$ and creates pores. This causes cell swelling and lysis, eventually leading to the death of the insect.

Which part of the insect's digestive tract is damaged by the $Bt$ toxin?
