Firefly luciferase is the light-emitting enzyme responsible for the bioluminescence of fireflies and some types of beetles. This process occurs in specialized light-emitting organs, usually on a firefly's lower abdomen. The enzyme catalyses the firefly chemical luciferin, by binding to it and spending up the chemical reaction that combines oxygen molecules to produce oxyluciferin. Besides, oxygen this requires ATP. Because of the requirement of ATP, firefly luciferases have been used extensively in biotechnology. How do the enzymes speed up the chemical reactions and produce bioluminescent light?

Answers

Answer 1

Answer:

Luciferase transforms luciferin into oxyluciferin while consuming ATP and O₂, and causes the emission of light.  

luciferin + ATP + luciferase + O₂ → oxyluciferin + AMP + CO₂+ luciferase + light

Explanation:

Fireflies are organisms that emit cold light by the process of bioluminescence. It is a chemical reaction of male individuals to attract the females that also respond by emitting light.

Luciferin is the molecule responsible for light emission. The chemical reaction involves the luciferin molecule, ATP molecule, enzyme luciferase, and oxygen molecule. Luciferin, the responsible molecule for light emission, is transformed into oxyluciferin by the enzyme luciferase. The enzyme consumes oxygen and ATP, which is the principal source of energy in living beings. Finally, a light of about 560 nm is released.

luciferin + ATP + luciferase + O₂ → oxyluciferin + AMP + CO₂+ luciferase + light

Almost the entire amount of energy involved in the reaction turns into luminous energy. ATP used for this light production process comes from the photosite´s mitochondrial electronic chain, responsible for the organism´s energy production.

Photosites are the cells responsible for light production, and many of their mitochondria are placed near the plasmatic membrane to catch oxygen.

Oxygen gets in the organisms through the lantern trachea. During the respiration process, photosites consume oxygen. Mitochondria placed in the cell periphery near the cell membrane catch the oxygen molecules and produce ATP. ATP produced by oxidative phosphorylation is involved in the production of oxyluciferin, turning into AMP.

Posteriorly, the oxyluciferin molecule is recycled back to luciferin. This process shows how chemical energy turns into luminous energy.

Define groundwater and explain how it relates to the terms water table, aquifer, and confined aquifer.​

Answers

Explanation:

Groundwater is water that occupies the zone of saturation within the ground. The water table is the upper limit of the groundwater. An aquifer is a body of porous rock or sediment saturated with groundwater. Groundwater enters an aquifer as precipitation seeps through the soil. It can move through the aquifer and resurface through springs and wells. Groundwater separated from atmospheric pressure by relatively impermeable material is termed confined groundwater. When such zones are penetrated by wells, the water rises above the point at which it was first found because a confined aquifer is under pressure exceeding that of atmospheric pressure.

what are possible consequences of complete dominance

Answers

Explanation:

In complete dominance, the effect of one allele in a heterozygous genotype completely masks the effect of the other. The allele that masks the other is said to be dominant to the latter, and the allele that is masked is said to be recessive to the former.

This pedigree supports the fact that the widow's peak is due to a dominant allele, because if it were due to a recessive allele and both parents show the recessive phenotype, then ________________________________. none of the sons would have a widow's peak none of the sons would have a widow's peak all of the daughters and none of the sons would have a widow's peak all of the daughters and none of the sons would have a widow's peak none of the daughters would have a widow's peak none of the daughters would have a widow's peak all of the offspring would have a widow's peak

Bauxite is an ore that is mined extensively. What makes bauxite a valuable ore?
A It is extracted for use in food.
B It is burned to generate electricity in power plants.
C It is the primary source for aluminum.
D It is used in the production of steel.

Answers

Answer:

C

Explanation:

Bauxite is the most common aluminum ore. Approximately 98% of primary aluminum production is based on bauxite. In the former Soviet Union, aluinite and kaolinite are also used in small proportions for aluminum production. Bauxite is a naturally occurring, heterogeneous material composed primarily of one or more aluminum hydroxide minerals plus various mixtures of silica, iron oxide, titania, and other impurities in trace amounts. The principal aluminum hydroxide minerals found in varying proportions within bauxite are gibbsite (trihydrated) and boehmite and diaspore (both monohydrated). The content of aluminum oxide is 30–60%. Bauxite is generally extracted by open cast mining from strata, typically 4–6 m thick under a shallow covering of topsoil and vegetation (Table I).

This fossil bird and this living salamander both have tails. However, they have different tail structures. The bird has a very short tail made of just one bone that helps it have a light skeleton for flying. The salamander has a long tail with many bones that helps it balance while it runs. What most likely explains why both the bird and salamander have tails and why the tails are different

Answers

birds like to lay fossils. Salamanders have tails btw.

Hope this helped!

The fossil bird and salamander both have different tail structure because they both inherited tails from a shared ancestor population initially, but this population eventually separated into different environments.

In order to adapt into their immediate environment they both evolve their tail structure to carry out different functions.

 

How does evolution occur? It is the change in the phenotypic characters  of a species over several generation resulting from natural selection and genetic drift.

The  the tail of salamander  was evolved to store fat and proteins, assistance in the movement, hence it has long tail with many bones for ease of movement.

Whereas birds short and light weight tail for the ease of flying and normal functioning.

Hence, different body structure evolved from the same ancestors for the adaptation in different species.

Answers

Banana and lemon that’s the answer

Based on the model, Banana and lemon are the pairs of species most likely have the greatest number of differences in their DNA and protein sequences. Thus, option B is correct.

What is DNA?

DNA contains the genetic information needed to determine the structure and function of living organisms. Each DNA molecule is found on a chromosome, and the segments of that DNA molecule are genes.

In somatic cells -such as nerve and muscle cells- the DNA sequences are the same, but what determines the synthesis of different proteins is the information that the genes have, i.e., fragments of DNA contained in a cell.

For this reason, nerve cells have a gene that allows them to synthesize the enzyme cholinesterase, while muscle cells have a gene that codes for myosin, even though they both possess the same DNA sequence.

Therefore, Based on the model, Banana and lemon are the pairs of species most likely have the greatest number of differences in their DNA and protein sequences. Thus, option B is correct.
