Midgut

Vedclass · Answer

(D) In insects,the digestive tract is divided into three parts: foregut,midgut,and hindgut. The $pH$ of the midgut is alkaline,which is essential for the activation of certain toxins,such as the $Cry$ protein produced by $Bacillus$ $thuringiensis$ $(Bt)$. When the insect ingests the $Bt$ toxin,the alkaline $pH$ of the midgut solubilizes the crystal protein,converting it into its active form,which then binds to the epithelial cells of the midgut and causes cell lysis,leading to the death of the insect.

In which part of the insect's body is the $pH$ alkaline?
