Bioluminescence is the natural phenomenon in which living organisms produce light through a chemical reaction in their cells . This process occurs in bacteria, algae, insects (such as fireflies), deep-sea fish, and fungi . Bioluminescence is being investigated as a possible sustainable, electricity-free light source .
How does bioluminescence work?
🔹 The chemical reaction takes place between luciferin (a light-emitting molecule) and luciferase (an enzyme) .
🔹 In the presence of oxygen and ATP (energy source in cells), light is emitted without heat production.
🔹 The color of the light varies from blue and green to red and yellow , depending on the organism and its chemical composition.
💡 Advantage: Bioluminescence provides light without electricity , making it an interesting option for sustainable lighting.
Applications of bioluminescence
