How fireflies light lanterns, how fireflies light lanterns

The luminescence principle of fireflies is:

Fireflies have specialized light-emitting cells, and there are two classes of chemicals in the light-emitting cells, one is called luciferin (in fireflies called firefly luciferin) and the other is called luciferase. Luciferin can consume ATP under the catalysis of luciferase and react with oxygen, which produces oxidized luciferin in the excited state, and releases photons when the oxidized luciferin returns from the excited state to the ground state.

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, and the reaction efficiency is 95%, so the beetle will not overheat and burn. So far, humans have not been able to create such an efficient light source.

There are many white patches on the lower part of the abdomen. In fact, it is the part of its carapace that is transparent to light. On the inside there is a white film that reflects light. So during the day this part appears white.

Luminous case. On July 14, 2014, Campground Elkmunt in Great Smoky Mountains National Park, Tennessee, USA, ushered in the annual firefly breeding and mating season, and countless fireflies flew in the air, lighting up the entire night sky, attracting thousands of visitors.

Tourists with red flashlights walk along the river and observe the "courtship ritual" of glowing fireflies. Luminescent fireflies, found only in Southeast Asia and parts of the Great Smoky Mountains in Tennessee, live for only 21 days as adults, using their glow to trap prey and attract mates. The park provides buses for visitors to see the glowing fireflies up close.

Fireflies lighting lanterns is an old saying.

Actually, it's courtship.

There are more than 2,000 species of fireflies in the world, which appear in summer, by rivers, ponds, and farmlands, and their range of activity generally does not leave 8 4 clean water sources

Officially, glow-worm refers to its larvae, while firefly refers to shiny adults, and male fireflies are more active and actively fly around to attract the opposite sex; The female perches on the leaf and waits for the signal

There is a phosphide luminescent substance in the body of fireflies, which will cause a series of chemical reactions through the action of luminescent enzymes, and the energy it emits is only about 1 percent of the heat energy, and the rest is changed into light energy, and its light is called cold light

Common fireflies have a light color between yellow and green, and no fireflies emit red. The male firefly has 2 glowing segments in the abdomen, and the female only has 1 segment The light is an energy-consuming activity, and it will not shine all night, and generally only lasts for 2 to 3 hours The adult lifespan is generally only 5 days to 2 weeks, and this time is mainly for mating and reproducing the next generation Fireflies are very active after 1 hour after sunset, buying time to pursue each other The male will flash a bright light in 20 seconds, wait for 20 seconds, and send out a signal again, patiently waiting for a strong light response from the female

The principle of fireflies lighting lanterns is because of the special luminescent chemistry on their bodies. The light-emitting organs in the body of fireflies contain luminescent enzymes, which produce light when the enzymes react with substances such as oxygen, ATP (adenosine triphosphate), and luciferin. The light of the fireflies comes in two colors, one is green and the other is yellow.

Both colors of light can be used for communication and mating of fireflies.

In addition to their special luminescence chemistry, fireflies are highly sustainable and are able to control their luminescence. In the body of fireflies, they can also sense information such as temperature changes, wind direction, and humidity in the outside world, so as to control the light emitting according to the situation. Fireflies emit light and does not affect the normal functioning of their bodies, as they do not need to consume a lot of energy to emit light.

In addition, the time and frequency of firefly lighting are also regular. Generally, fireflies are lit at night or dusk, and they don't light lanterns all at once, but flicker like lightning at random. This irregular flickering pattern can attract fireflies of the opposite sex for the purpose of mating.

In general, the principle of firefly lighting is driven by the special luminescent chemistry on their body, and they can also control the time and frequency of light emitted by external information. In addition, the way they glow can also attract fireflies of the opposite sex to achieve the purpose of mating. <>

Fireflies rely on their inner chemistry to light up their bodies. This phenomenon is known as bioluminescence or bioluminescence. Fireflies can emit light through a process called bioluminescence, which is called cold light because it doesn't produce a lot of heat.

This is a very special chemical reaction that only a few organisms can perform.

Fireflies contain a compound called fluorescein in their bodies. When luciferin and oxygen are combined, the enzyme (called luciferase) is activated, producing a high-energy intermediate product rich in chemical energy, isophenedione, and a large number of oxidoreductases. These chemical reactions continue in the firefly's body until the fluorescein is depleted or the enzyme is inactivated.

During this reaction, a large amount of chemical energy is released and is converted into light energy.

In addition, the body of fireflies is called the light organ, and this light organ also contains a special substance called metal phthalocyanine chelate, which is also an important factor in the body of fireflies to emit light. The presence of these substances causes the light of fireflies to turn into a distinctive yellow-green or green color.

Overall, the mechanism by which fireflies emit light is a very wonderful chemical reaction. This response is difficult to fully simulate or interpret because it relies on specific compounds inside the firefly's body, as well as very complex biological processes.

The luciferin in the luminescent cells of fireflies consumes ATP under the catalysis of luciferase and reacts with oxygen, which produces an excited state of oxidized luciferin, which releases photons when the oxidized fluorescein returns from the excited state to the ground state, thereby emitting light. <

The principle of luminescence of fireflies: Fireflies have specialized light-emitting cells, and there are two types of chemicals in the light-emitting cells, one is called luciferin (called firefly luciferin in fireflies), and the other is called luciferase. Luciferin can consume ATP under the catalysis of luciferase and react with oxygen, which produces an excited state of oxidized luciferin, which releases photons when it returns from the excited state to the ground state, thus emitting light.

When fireflies light up their bodies, they are actually performing a natural phenomenon called "bioluminescence". Fireflies contain a chemical called fluorescein, which emits light when it combines with oxygen in the air, which is how fireflies light up.

When fireflies are lit, they usually store energy from the inside of their body and then convert this energy into fluorescein to emit light. They convert fluorescein into two different substances, oxidase and luciferone, through chemical reactions in the body. Then, under the catalytic action of the body, the luciferin ketone will be converted into fluorescein, and the fluorescein will bind to oxidase, resulting in a blue-green luminescence.

Different species of fireflies exhibit different colors of light due to the different fluorescein in their bodies. In addition, fireflies will also adjust when they are lit, such as controlling the time of light and the brightness of the light, which are controlled by the nervous system in their body.

In addition to fireflies, many insects, plankton, and marine organisms are capable of "bioluminescence". This phenomenon is called "bioluminescence" because it does not emit heat like other luminescence phenomena, but emits light through a chemical reaction. The luminescence phenomenon in many organisms also has different functions, such as sucking to attract the opposite sex, dispel predators, and so on.

In short, the principle of fireflies lighting lanterns is to use fluorescein in the body to carry out a chemical reaction to emit light, and this phenomenon is called "bioluminescence". Through in-depth research, we can also discover the wonders of biological diversity. <>
