Question

Why do fire flies glow at night?​

Answer 1

Fireflies produce a chemical reaction inside their bodies that allows them to light up. This type of light production is called bioluminescence. ... When oxygen combines with calcium, adenosine triphosphate (ATP) and the chemical luciferin in the presence of luciferase, a bioluminescent enzyme, light is produced.

Answer 2

Fire flies glow at night because they have a protein in their bodies. The protein in the presence of an enzyme undergoes aerial oxidation. This is a chemical reaction which occurs with the emission of light. Therefore, fire flies glow at night.
