How does a firefly create light?
The light that a firefly creates is the result of a combination of four different ingredients. This light is produced through a chemical reaction involving Luciferin, which is a substrate, Luciferase, an enzyme, ATP, and oxygen . The light producing section of the body is located in the sixth or seventh abdominal section of the firefly. It is within this cavity that the two compounds Luciferin and Luciferase are stored. A firefly will draw oxygen in through its complex system of air tubes and expose the oxygen to the Luciferin and the Luciferin will then oxidize and activate the Luciferase. This will generate a light that will shine through the skeleton of the abdomen. It is important to note that scientists disagree about the method that the fireflies use to control the duration of their flashes. One theory, known as the “Oxygen Control Theory”, explains that fireflies can control the length and duration of their light by regulating the amount of oxygen that they intake . If little or
