Bioluminescence is defined as light emission produced due to which process?

Explanation:
Bioluminescence is light produced by a chemical reaction, specifically an enzyme-catalyzed oxidation of a substrate (such as luciferin) that releases photons. This means the energy comes from the chemical reaction itself, not from external light exciting the molecule. That’s why it’s different from fluorescence, where electrons are excited by radiant energy and then release light as they return to their ground state. It also doesn’t rely on radioactive labels. The defining idea is enzymatic oxidation producing visible light directly from chemical energy.
