What is the light-emitting process in deep-sea creatures caused by luciferin and luciferase?
Answer
Bioluminescence
Bioluminescence is light produced by organisms through a chemical reaction between luciferin (the light-emitting compound) and luciferase (the enzyme catalyst). When luciferin combines with oxygen in the presence of luciferase, it undergoes oxidation that releases light energy. Remarkably efficient, this 'cold light' reaction converts nearly all energy to light rather than heat. About 80% of deep-sea animals between 200-1,000 meters depth are bioluminescent, primarily emitting blue-green light that travels farthest underwater.
💡 Did you know?
Bioluminescent organisms use about 40% of their metabolic energy for light production—yet it produces almost no heat.
