How fireflies convert chemical energy into light energy

Food (organic matter) has chemical energy.

Fireflies rely on phosphorus-containing luminescent matter and luminescent enzymes in light-emitting cells to emit light, and phosphorus-containing luminescent matter and luminescent enzymes produce a chemical reaction, which has a very high luminescence efficiency of up to 95%.

There is a luminescent device at the end of the firefly's abdomen, which is filled with phosphorus-containing luminescent matter and luminescent enzymes, and when the firefly breathes, the fluorescein is oxidized and synthesized luciferase by inhalation, and the firefly emits light. Fireflies have a very high luminescence efficiency, which can convert almost all chemical energy into visible light, and it is a cold light with almost no thermal radiation and no magnetic field.

The purpose of fireflies to glowThe bright light emitted by fireflies is not only for lighting, but mainly for signaling, and the signal emitted by each purpose is different. Different species of fireflies emit different frequencies, brightness, ways and colors of light, and most of the fireflies we usually come into contact with are yellow-yellow or green-green glowing. It can be said that this is the language of fireflies, just like the sos** of humans, such as courtship, vigilance, trapping, and communication with their own kind, all of which are communicated in this way.

Fireflies rely on chemical reactions in light-emitting cells to emit light, and this reaction has a very high luminescence efficiency of up to 95%. In other words, almost all of the energy released in the reaction is converted into light energy, and only a very small part is released in the form of heat energy.

Therefore, the temperature of fireflies is very low, and it is a natural and efficient cold light source. In stark contrast, only about 10% of the energy of incandescent lamps used by humans is converted into light, and the remaining energy is wasted as heat, and other halogen tungsten lamps and arc lamps are also included.

Firefly luminescence principle

In nature, many plants and animals have the ability to emit light, and this phenomenon of biological luminescence is also known as "bioluminescence". There are two main types of bioluminescence, one is that the organism itself has a luminescent device and can control the luminescence independently, and the other is that the organism does not have a specialized luminaire and needs to live in symbiosis with luminescent bacteria or be parasitic and emit light, and does not have the ability to control.

Except for some diurnal species of fireflies that cannot emit light, most firefly eggs, larvae, pupae and adults can emit dazzling light. Due to the different growth stages of fireflies, the location of the luminaires is also different, the luminaires of the larvae are located on both sides of the 8th segment of the abdomen, and the luminaires of the pupal are very similar to those of the adults, both in the 1 2 segments at the end of the abdomen.

Chemical changesThe glow on the belly of a firefly has a light emitting layer in the shape of a small window. These light-emitting layers contain thousands of light-emitting cells that contain two types of chemicals, one called luciferin (an organic compound that can be synthesized artificially) and the other called luciferase (simply a catalyst). Luciferin can react with oxygen in the air under the catalytic action of luciferase, release energy, and fluoresce (energy exists in the form of photons).

So, fireflies emit light because of chemical changes.

Almost all of the energy released in the reaction is released in the form of light, and only a very small part is released in the form of heat, so the light of fireflies belongs to cold light, and fireflies will not burn themselves due to overheating of their bodies. Fireflies produce this cold light with an efficiency of more than 95%, and humans have not been able to produce such an efficient light source so far.

The ** of energy is food, after the food is digested, the nutrients enter the cells and are converted into all kinds of organic matter Animal cells then release the energy stored in the organic Wang Pai through respiration, in addition to a part of the conversion into heat energy, the rest is stored in ATP for the needs of animals to carry out various life activities Fireflies fly among the trees, and the fluorescent light is very beautiful, because part of the energy released by fireflies is converted into light energy

Therefore, the answer is simply as follows:

Because of the firefly's own factors, there are some chemicals in its abdomen that can make it glow; Matches cannot be lit because fireflies do not have anything of their own that would make them burn.

This is because fireflies have chemicals in their bodies that can emit light, which is a light-emitting element that contains phosphorus, so it will shine and it is impossible to light a match.

The light source of the firefly mainly comes from some chemicals in his body, which does not carry any heat and does not have any possibilities, so it is not allowed to light matches.
