Detailed explanation-1: -To generate visible light, cells in a firefly’s tail produce thousands of luciferase enzymes. Luciferase binds to a chemical called luciferin. Once bound, the luciferase enzyme speeds up a chemical reaction that combines an oxygen molecule and luciferin to produce oxyluciferin.
Detailed explanation-2: -This reaction requires energy and releases light. The luciferase speeds up the reaction, which occurs in two steps: The luciferin combines with adenosine triphosphate (ATP), found in all cells, to form luciferyl adenylate and pyrophosphate (PPi) on the surface of the luciferase enzyme.
Detailed explanation-3: -Bioluminescence is a form of chemiluminescence, which is the production of visible light by a chemical reaction. When this kind of reaction occurs in living organisms, the process is called bioluminescence. It is familiar to most of us as the process that causes fireflies to glow.
Detailed explanation-4: -Firefly luciferin, as its name implies, the molecule is essential for fireflies to emit light. The catalyst for the light-producing reaction is the enzyme luciferase, which may be useful in the quest for testing for COVID-19 infections and for developing drugs to combat the disease.
Detailed explanation-5: -The chemical reaction catalyzed by firefly luciferase takes place in two steps: luciferin + ATP → luciferyl adenylate + PP. luciferyl adenylate + O2 → oxyluciferin + AMP + light.
