C6H12O6 (glucose) + O2 (oxygen) -> CO2 (carbon dioxide) + H2O (water) + sunlight energy (ATP). The reaction is called cellular respiration and it is used in plants and animals to break down sugars into usable energy to complete bodily functions.

Explanation:

A chemical reaction is defined as the process in which one or more substances reacts to form one or more products which are chemically transformed means the constituent atoms of the reactants are rearranged unlike physical reactions. No new atoms are created or destroyed, bonds between the atoms in the reactants are broken and the atoms rearrange themselves and form new bonds to make the product. For example iron and oxygen combine to form rust, sodium acetate is formed by the combination of vinegar and baking soda etc.

Cell respiration involves different steps, among which there is the oxidative phosphorilation that produces and stores ATP. The answer is the <u><em>electron transporter chain</em></u>.

<h3>ELECTRON TRANSPORTER CHAIN -oxidative phosphorylation-</h3>

The electron transporter chain + chemiosmosis constitute the process of oxidative phosphorylation.

Chemiosmosis

Chemiosmosis refers to ATP production through a proton gradient.

Electron transporter chain

The electron transporter chain is a series of molecules and proteins located in the internal mitochondrial membrane.

It constitutes a series of enzymatic reactions to release and save energy for the correct functioning of the organism.

Along the chain, there are four proteinic complexes in the membrane, I, II, III, and IV, that contain the electrons transporters and the enzymes necessary to catalyze the electrons' transference from one complex to the other.

Different redox reactions occur to pass electrons along the chain.

Released energy creates a proton concentration gradient used to synthesize ATP.

<h3>Steps in the electectron transporter chain</h3>

1) NADH provides electrons to the first complex, Complex I. From there, electrons go to the coenzyme Q that carries them to complex II. Meanwhile, complex I pomp four protons to the intermembrane space.

2) Complex II receives electrons from CoQ and also receives electrons from FADH2. Electrons are sent from complex II to ubiquinone Q, which carries these electrons to complex III.

3) Complex III receives electrons from ubiquinone Q and pomps protons to the intermembrane space. Electrons are transferred to Cytochrome c.

Electrons travel from cytochrome c to complex IV.

4) Complex IV is the last complex that pomps protons to the intermembrane space.

5) Electrons are sent to O₂ molecules, which also receive protons in the matrix to create water molecules. Four electrons are needed to produce two water molecules from one O₂ molecule.

The proton gradient is used to produce ATP molecules.

In conclusion, <em>the set of proteins in the cristae of the mitochondrion, which collectively extract the energy from reduced coenzymes to form atp, are called the</em> <u><em>electron transporter chain</em></u>.

What is the main function of environmental policy?

kenny6666 [7]

The main function of environmental policy is to <u>reduce human impact on the environment (B). </u>

<h3>Further explanation </h3>

Humans impact the environment in so many ways such as overpopulation, overfishing, pollution, and deforestation. This condition leads to many other problems: poor air and water quality, climate change, and soil erosion. Increasing population means increasing demand for consumption that may destroy the natural resources and environment.

The government or an organization creates environmental policies to regulate environmental issues and to reduce human impact on the environment. According to McCormick environmental policy is “any action deliberately taken to manage human activities to prevent, reduce, or mitigate harmful effects on nature and natural resources, and ensuring that man-made changes to the environment do not have harmful effects on humans or the environment.”

The policy regulates the use of resources and to reduce pollution to promote human welfare and protect natural resources. Some example of environmental policy, governments forbade the use of hazardous substances in agriculture or apply maximum emission levels for the industry to ensure minimum environmental quality.

The earliest classification systems grouped organisms based on

Paul [167]

Answer:

On the basis of physical traits.

Explanation:

Newer classification systems classify organisms on the basis of physical traits of an organism. All modern classification systems gets their concept and help from Linnaean classification system. In these new classification systems, those organisms that have similar characteristics are placed in one group because they evolve from the same ancestor or having common ancestry. These changes occurs in the organisms with the passage of time that helps organisms to survive in that environment.
