LUCIERNAGA EN BOMBILLA

¿Cómo puede iluminar una luciérnaga?

La luciérnaga es el único insecto que puede volar e iluminar. Habita en bosques y humedales, donde la iluminación le sirve para reproducirse, alimentarse y evitar a los predadores. Su eficiencia luminosa es mucho mayor que la de las lámparas eléctricas, pero ¿cómo puede ser esto posible? Pues bien, a la emisión de luz por parte de un organismo vivo se le llama bioluminiscencia: bio (del griego) significa vida y lumen (del latín) quiere decir fuente de luz. Consiste en una reacción química que se produce entre el oxígeno y un sustrato llamado D‑luciferina. Para que se produzca esta reacción es necesaria la presencia de la enzima luciferasa, que permite la formación de un compuesto inestable que pronto se descompone dando oxiluciferina y liberándose fotones de luz visible de color amarillo‑verdoso.

How can fireflies glow?

Fireflies are the only insects that can both fly and glow. They live in forests and wetlands. Their glowing helps them to reproduce, feed and avoid predators. Their luminous efficiency is far better than that of electric lamps. Do you want to know how this is possible? Well, the emission of light by a living organism is called bioluminescence. Bio comes from Greek and means life. Lumen comes from Latin and stands for light. The bioluminescence phenomenon consists of a chemical reaction between the oxygen and the substrate called D-luciferin. This reaction requires the presence of the enzyme luciferase to occur and allows the production of an unstable compound. The latter breaks soon down into oxyluciferin, a process that takes place by the release of photons of visible yellow greenish light.
