What makes lightning bug light up?
Fireflies or lightning bugs make light within their bodies. This process is called bioluminescence and is shared by many other organisms, mostly sea-living or marine organisms. Fireflies light up to attract a mate. To do this, the fireflies contain specialized cells in their abdomen that make light. The cells contain a chemical called luciferin and make an enzyme called luciferase. To make light, the luciferin combines with oxygen to form an inactive molecule called oxyluciferin. The luciferase speeds up the reaction, which occurs in two steps: # The luciferin combines with adenosine triphosphate (ATP), which is found in all cells, to form luciferyl adenylate and pyrophosphate (PPi) on the surface of the luciferase enzyme. The luciferyl adenylate remains bound to the enzyme: luciferin + ATP -------------> luciferyl adenylate + PPi# The luciferyl adenylate combines with oxygen to form oxyluciferin and adenosine monophosphate (AMP). Light is given off and the oxyluciferin and AMP are released from the enzimes` surface. luciferyl adenylate + O2 -------------> oxyluciferin +AMP + light

How do fireflys make 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 no oxygen reaches the part of the firefly known as the phonic organ, the chemical reaction will not be extremely strong and the light of the firefly will not shine very brightly or for a lengthy duration. Another theory, known as the "Neural Activation Theory" states that fireflies have neural control over the activity of structures called "tracheal end cells" . These structures aid in the initiation of the chemical reaction. Whether or not the fireflies have physical or neural control over their ability to produce light, their method of creating the light that emanates from their bodies is extremely efficient. Very little heat is given off of this light which means that not very much energy is wasted at all. This "cold light" has a 96% efficiency rating; which, when compared to an incandescent light that has only 10% efficiency, is rather impressive.
Where can you buy live fireflies?
godofinsects.comFamily LampyridaeFirefliesFireflies, also known as "lightning bugs", are beetles belonging to the family Lampyridae. The use of the word "lamp" in their family name aptly illustrates the extraordinary characteristic that elevates fireflies to such a beloved position in the minds of humans. Anyone who has not witnessed a light show put on by fireflies has been deprived of one of the great wonders of the natural world. A firefly's ability to create light stems from a controlled chemical reaction inside the abdomen of the firefly. Luciferin (a highly florescent substance) is combined with Luciferase (an enzyme), ATP (adenosine triphosphate) and oxygen in order to alter the Luciferin molecule so that its excited electrons produce florescent illumination. This "cold light" (containing no ultra violet rays) is used for communication. Fireflies generally flash at dusk and each species has it's own way of communicating using these flashes of light. There are some diurnal species of fireflies but many of them have no ability to produce light. Fireflies in both the Old and New World use flashes of light from their abdomen for communication between the sexes. In the Old World, many fireflies aggregate in species-specific swarms of males that flash in synchronicity. In the New World, this is rare and the males generally fly around and flash over open areas, like fields or forest clearings, searching for a female. Females wait on the ground or on low vegetation and offer the proper response if they see a mate they like. A dialogue of flashes ensues which helps the male locate the female and make sure she's the same species as him. In the New World, this courtship rite has turned dangerous because fireflies in the genus Photurishave learned to imitate the flashes of other species. Using this ability, males of other species that are out seeking mates are lured in close and then captured and eaten. The behavior ofPhoturis is singular and most other species of fireflies either feed on plant fluids and pollens or live off stores of larval fat. The larvae of fireflies are also capable of producing light and are called glow worms. In contrast to the adults, most glow worms are predatory. Many species are associated with moist habitats and a few Asian species are fully aquatic. It has been surmised that glow worms produce light as a warning since many are poisonous. Adults of many species are also poisonous. In some species of fireflies the females are wingless and, in looking just like the larvae (except for their compound eyes), are also called glow worms. In North America, the Rocky Mountains serve as barrier which has kept most light-producing species in the east. For those who live in the western part of the U.S.A., light-producing species can be found if you look but they are limited in distribution due to moisture requirements. These western species are found in close association with moist forests and along the banks of rivers in the more arid regions. · We do not sell live fireflies for release at weddings.
The movement of which kind of molecule is controlled by osmosis?
The solvent, usually water.
What animal has bioluminescence?
When the seal in the stick is broken, the two chemicals mix together and give off a soft, green glow. Most of the light created by marine organisms is blue-green in colour. This is because blue light travels best in water, and because most marine organisms are sensitive to blue light.
How do lantern fish light up their lights?
Bioluminescence is the production and emission of light by a living organism. It is a form of chemiluminescence. Bioluminescence occurs widely in marine vertebrates and invertebrates, as well as in some fungi, microorganisms including some bioluminescent bacteria and terrestrial invertebrates such as fireflies. In some animals, the light is bacteriogenic, produced by symbiotic organisms such as Vibrio bacteria; in others, it is autogenic, produced by the animals themselves.In a general sense, the principal chemical reaction in bioluminescence involves some light-emitting molecule and an enzyme, generally called the luciferin and the luciferase, respectively. Because these are generic names, the luciferins and luciferases are often distinguished by including the species or group, i.e. Firefly luciferin. In all characterized cases, the enzyme catalyzes the oxidation of the luciferin.In some species, the luciferase requires other cofactors such as calcium or magnesium ions, and sometimes also the energy-carrying molecule adenosine triphosphate (ATP). In evolution, luciferins vary little: one in particular, coelenterazine, is found in eleven different animal (phyla), though in some of these, the animals obtain it through their diet. Conversely, luciferases vary widely between different species, and consequently bioluminescence has arisen over forty times in evolutionary history.Both Aristotle and Pliny the Elder mentioned that damp wood sometimes gives off a glow and many centuries later Robert Boyle showed that oxygen was involved in the process, both in wood and in glow-worms. It was not until the late nineteenth century that bioluminescence was properly investigated. The phenomenon is widely distributed among animal groups, especially in marine environments where dinoflagellates cause phosphorescence in the surface layers of water. On land it occurs in fungi, bacteria and some groups of invertebrates, including insects.The uses of bioluminescence by animals include counter-illumination camouflage, mimicry of other animals, for example to lure prey, and signalling to other individuals of the same species, such as to attract mates. In the laboratory, luciferase-based systems are used in genetic engineering and for biomedical research. Other researchers are investigating the possibility of using bioluminescent systems for street and decorative lighting, and a bioluminescent plant has been created
Why do cells have a variety of different transport mechanisms across the cell membrane?
Cells need to regulate each substance so its import and export is controlled. If there would be one mechanism to import every substance, the concentration of any individual molecule couldn't be controlled.
