Carbon is one of the elements that are involved in the biogeochemical cycle.

One way carbon moves from the atmosphere to the biosphere is through a process by which plants use light energy and convert it into biochemical energy. This process is called photosynthesis. Plants use energy from the sun to combine carbon dioxide and water to form glucose.

In photosynthesis, six molecules of carbon dioxide react with six molecules of water to produce oxygen and glucose as follows;

6CO2 + 6H2O ---->C6H12O6 + 6O2. The products of photosynthesis are glucose and oxygen.

Carbon is incorporated  into the carbon cycle via water in the hydrosphere when carbon dioxide dissolves into oceans as the bicarbonate ion. The oceans serve as the largest reservoir of carbon. About 37,000 billion tons of carbon are stored in the oceans out of  about 65,500 billion tons of carbon available globally.

Proteins, nucleic acids, lipids, and carbohydrates are based on carbon. Carbon is contained in all biological molecules which makes it very important in biochemistry.

Photosynthesis is a chemical reaction as shown above. It occurs in the chloroplasts of plant cells which is able to trap energy from the sun in order for the process of photosynthesis to take place.

The reservoirs that make up the carbon cycle are four;

Carbon is transferred from the atmosphere to the biosphere by photosynthesis when green plants absorb carbon in order to produce biomass. The overall scale of the carbon cycle is planetary.

Different stimuli of the two special senses trigger different methods of signaling within their receptors. They are:

Our sensory receptors may number closer to 18 or 20, according to scientists. Chemoreceptors react to substances through taste, odor, and internal alterations. When the temperature changes, thermoreceptors react. Mechanoreceptors react to pressure, touch, and other physical forces.

The physical cues for taste are soluble chemical molecules found in food and fluids, and various molecules trigger various sensory receptors. When food is put in the mouth, molecules in it dissolve in saliva and come into touch with taste buds, which triggers the first taste sensation.

Hence, Exteroreceptors: They react to inputs from the outside world. Our bodies contain interoceptors, which react to any alterations in the internal environment, such as variations in temperature, blood pH, and so forth.

The processes that would occur at higher rates in the fed (absorptive) state than in the fasted (postabsorptive) state are:

- Conversion of glycogen to glucose in muscle cells

- Synthesis of protein by muscle cells

- Oxidation of glucose by muscle cells

The conversion of glycogen to glucose in muscle cells occurs during the absorptive state as glucose is taken up from the bloodstream and stored as glycogen in the muscle cells. In the postabsorptive state, glycogen is broken down into glucose to maintain blood glucose levels.

Synthesis of protein by muscle cells also occurs during the absorptive state when there are high levels of amino acids available from dietary protein. In the postabsorptive state, protein breakdown may occur to provide amino acids for energy.

Oxidation of glucose by muscle cells is also higher during the absorptive state as glucose is readily available from the diet. In the postabsorptive state, glucose levels may be lower, and alternative fuel sources like fatty acids may be used for energy instead.

The other processes mentioned, conversion of triglycerides into glycerol phosphate and fatty acids in adipocytes, and oxidation of lipids by liver cells, are more likely to occur during the postabsorptive state when stored energy sources like fat are used for fuel.

Animal cells lack chloroplasts; exclusively plant cells contain. The production of sugars, which power the cell's mechanism, is the role of the chloroplast.

Cells are the essential building blocks of all living things. There are two different types of cells: prokaryotic cells, which lack a nucleus but still possess a nucleoid area, and prokaryotic organisms, which have a nucleus. They provide the body with structure, take in nutrients from food, convert that energy in and out of electricity, and carry out certain functions.

Scientists once believed that life organically evolved from inanimate substances. As a consequence of investigations and the invention of the microscope, it is now understood that cells arise from preexisting cells and that life derives from earlier life. Cells mostly come into one of two categories: prokaryotic or eukaryotic.

As an AI language model, I cannot generate an image or diagram to place labels in their respective targets, but I can describe how mRNA is stored in a translationally inactive state.

mRNA molecules can be stored in a translationally inactive state through various mechanisms. One common method is the binding of regulatory proteins to specific sequences in the mRNA molecule known as untranslated regions (UTRs).

These proteins can prevent the ribosome from binding to the mRNA molecule, thereby inhibiting translation. Additionally, mRNA molecules can be stored in specialized structures called processing bodies (P-bodies), which contain enzymes that degrade mRNA molecules.

In P-bodies, mRNA molecules are sequestered away from ribosomes, preventing translation. Finally, mRNA molecules can be stored in a complex with RNA-binding proteins, which can inhibit translation by masking the ribosome-binding site or promoting degradation of the mRNA molecule.

Overall, the mechanisms used to store mRNA in a translationally inactive state serve important roles in regulating gene expression and ensuring that protein production is tightly controlled within cells.

The lack of experimentation involving the insertion of genes can be attributed to a number of factors. One of the primary reasons for the lack of these experiments is the fear of the unknown.

There is a great deal of uncertainty surrounding the potential consequences of genetic modification, and the ethical implications of such experiments are far-reaching. The potential health risks of gene insertion are not fully understood, and this lack of knowledge has led to a great deal of fear and caution among the scientific community.

While some studies have indicated that gene insertion could have the potential to treat or cure certain diseases or illnesses, there is a lack of conclusive evidence demonstrating the safety of the process. Moreover, there is concern that gene insertion could lead to the development of new diseases or mutations, with unknown consequences.

Furthermore, the ethical implications of gene insertion are highly contested. Due to the fact that genetic modification can be passed down across generations, there is a fear that the modification could be inherited by future generations. This has led to heated debates about the morality of gene insertion and its potential implications for generations to come.
