Ch 1 · The chemistry of living light
teacher Hey there, did you know, deep under the blue, oh-oh, Light can be made, cool and anew, yeah! It's a chemical dance, no heat to burn, oh-oh, Cold light shining, lessons we learn!
Fun Fact
Cold light efficiency: Bioluminescent creatures convert nearly 100 percent of their chemical energy into light, leaving virtually zero waste heat.
Glossary
luciferin (noun)
An organic compound that emits light when oxidized in the presence of a specific enzyme. In 1887, French physiologist Raphaël Dubois first extracted this substance, which enables marine organisms to glow.
