DEF

Emission of light as a consequence of the cellular oxidation of some substrate (luciferins) in the presence of an enzyme (luciferases). It is present in bacteria, fungi, protozoa, and species belonging to 40 different orders of animals.

CONT

Bioluminescence results from a chemical reaction (chemiluminescence) in which the conversion of chemical energy to radiant energy is direct and virtually 100 percent efficient; i.e., very little heat is given off in the process. For this reason the emission is called cold light, or luminescence.
