Question

Why does the insecticidal protein produced by Bacillus thuringiensis not kill the bacterium, but kills the cotton bollworm? Explain.

Answer 1

Answer:

Hey mate here is your answer.

Explanation:

The Bt toxin protein exists as inactive protoxin. Once an insect ingests the inactive toxin, it is converted into an active form of the toxin due to the alkaline pH of the gut which solubilises the crystals. Therefore, it does not kill the bacteria.
