Vedclass · Answer

(C) $Bacillus$ $thuringiensis$ $(Bt)$ produces a specific type of insecticidal protein known as the $Cry$ protein or $Bt$ toxin.This protein is produced in an inactive protoxin form within the bacterium.When an insect ingests the $Bt$ toxin,the alkaline $pH$ of the insect's gut solubilizes the crystals,converting the protoxin into its active form.The active toxin binds to the surface of the midgut epithelial cells,creating pores that cause cell swelling and lysis,eventually leading to the death of the insect.

What does $Bacillus$ $thuringiensis$ produce that is responsible for the death of certain insects?
