11. In the luciferase reaction, light is emitted when luciferase acts on the appropriate luciferin substrate. 12. Two chemicals, luciferin and luciferase that react with one another to create a soft glow. 13. In 2006 Azaghal recorded a second album for Avantgarde Music, " Luciferin Valo ". 14. Fireflies, anglerfish, and other organisms produce the light-emitting pigment luciferin and the enzyme luciferase. 15. When luciferin reaches cells that have been altered to carry the firefly gene, those cells emit light. 16. Both luciferases require the addition of an exogenous substrate ( luciferin ) for the light reaction to occur. 17. When the pH drops, luciferase changes its shape, allowing luciferin , more specifically tetrapyrrole, to bind. 18. The technique requires luciferin to be added to the bloodstream, which carries it to cells throughout the body. 19. The insect can regulate its light production by controlling the oxygen supply to the light emitting membranes containing luciferin . 20. Bioluminescent organisms are capable of producing light biologically through the agitation of molecules of luciferin , which then produce light.
