The intestinal enzyme that converts trypsinogen to trypsin is: MCQ with Answer and Explanation

Explanation:
Bacillus thuringiensis (Bt) is widely used as a biopesticide, specifically a bioinsecticide. The spores of Bt contain crystalline proteins (Cry toxins) that are toxic to the larvae of many insects, particularly Lepidoptera (caterpillars), Diptera (flies), and Coleoptera (beetles). When sprayed on crops or ingested by transgenic plants, these toxins kill the pests without harming humans, animals, or beneficial insects.

Explanation:
Lysozyme, an enzyme found in tears, saliva, and egg white, hydrolyzes the β-1,4-glycosidic bond between N-acetylmuramic acid and N-acetylglucosamine in peptidoglycan, weakening the bacterial cell wall and causing lysis. It is part of innate immunity. Penicillin inhibits peptidoglycan synthesis.

Explanation:
Light reactions occur in thylakoid membranes, producing ATP, NADPH, and oxygen. Oxygen comes from water (photolysis), not CO₂. So statement 2 is incorrect. 1 and 3 are correct.
