Carbon has four electrons in its valence shell (outershell). Since this energy shell can hold eight electrons, each carbon atom can share electrons with up to four different atoms. Carbon can combine with other elements as well as with itself. This allows carbon to form many different compounds of varying size and shape.

How does carbon enter the biotic parts of the biosphere during the carbon cycle?
Carbon, in the form of carbon dioxide, enters living things from the nonliving environment when plants and other producers photosynthesize. Carbon returns to the environment when living things respire, are decomposed, or are burned (combustion).
What process does deep sea organisms depend on?
A lot of organisms that thrive in the deepest parts of the ocean rely heavily on chemosynthesis. Chemosynthesis is most commonly seen near thermal vents and involves the biological conversion of 1+ carbon molecules (methane/CO2) and nutrients into organic matter. This is made possible through the oxidation of inorganic molecules such as H2 or Hydrogen Sulfide; these are used as a source of energy, rather than radiation from the sun.
What are the two parts of the backbone of DNA?
The two parts of the backbone of DNA are sugar and phosphate molecules. These molecules alternate in a pattern, forming the structure of the DNA double helix.
Are organic compounds produced only in organisms?
Organic molecules are most abundantly found inside living organisms, but they are dispersed throughout the world's biosphere; in addition, there are interstellar gas clouds which contain organic molecules, and the atmosphere of some of the moons in the outer solar system is known to contain organic molecules, and there are likely to be many other places in the universe where we haven't looked yet, that also contain organic molecules.
What are (subunits) called -?
Nucleotides are molecules consists of three parts-a nitrogen base, a five-carbon sugar and a phosphate group. DNA and RNA are made of the subunits called nucleotides.
What is the difference between organic chemistry and inorganic chemistry?
Generally speaking, Organic chemistry deals with carbon based molecules,(these molecules will often contain: Carbon, oxygen. nitrogen and hydrogen) while inorganic deals with everything else. . Organic chemicals have a carbon based skeleton which provides the framework of the molecule. Of course there are parts of each branch of chemistry that overlap and all branches are connected through the natural laws that govern the behavior of all atoms and molecules.
How is carbon in living things?
Carbon makes molecules of all sorts. Just about anything that grows has carbon molecules in many parts of their bodies. Just one example is sugar. In one form, Sugar is the food for the brain.
What are the different parts of a molecule?
A molecule consists of atoms bonded together through chemical bonds. The main parts of a molecule include atoms, which are the building blocks of matter, and bonds, which are the forces holding the atoms together. Various types of molecules can exist, such as organic molecules containing carbon atoms and inorganic molecules without carbon atoms.
How are carbon films preserved remains different?
carbon films can preserve the delicate parts of plants leaves and insects, and preserved remains can preserve entire organisms.
Where does the term carbohydrate come from referring to the parts of the word?
The term "carbohydrate" comes from the chemical composition of these compounds, which consist of carbon, hydrogen, and oxygen molecules. The "carbo-" prefix refers to carbon, while the "-hydrate" suffix suggests the presence of water molecules in the structure.
Characteristics of organic molecules?
organic molecules characteristics :1) Based on carbon .carbon atoms gives the ability to do long chains , branches and rings .2) form from few elements.99.4 % carbon , hydrogen , nitrogen , and oxygen , 0.2% phosphorous, 0.2% calcium , and 0.2% all other elements3) modular structures form from simple buildings blocks .long and complicated molecules can be put together in twocontrasting ways.the first : by build each one from scratch , so that no piece of one molecules be art of another , the second : to build a succession simpler , widely available parts , so that each large molecule differs from another only in the arrangement of those parts.4) chemical function is determined by their geometric shape.
What are the three parts of a bond?
The three parts of a bond is atoms, molecules, and ions. The three parts of a bond is atoms, molecules, and ions. The three parts of a bond is atoms, molecules, and ions.
What are the four parts a triglyceride?
You have three molecules of fatty acids and one molecule of glycerol. The fatty acids are usually have 16 to 20 carbon atoms in them.
What is the simple definition of a carbon reservoir and how does it play a role in the Earth's carbon cycle?
A carbon reservoir is a place where carbon is stored, such as the atmosphere, oceans, soil, and living organisms. It plays a crucial role in the Earth's carbon cycle by regulating the amount of carbon in different parts of the environment, helping to maintain a balance of carbon dioxide in the atmosphere and supporting life on Earth.
Are RNA molecules are made of nucleotides?
Yes. Ribonucleic acids, also called RNA, is the intermediary molecule used by organisms to translate the information in DNA to proteins. RNA is a polymer - made up of chains of nucleotides which have three parts: A five-carbon ribose sugar A phosphate molecule One of four nitrogenous bases: adenine, guanine, cytosine, or uracil
What are the two main parts of the oxygen cycle?
The two main parts of the oxygen cycle are the process of photosynthesis, where plants produce oxygen as a byproduct, and the process of respiration, where living organisms consume oxygen and release carbon dioxide.
How are organisims named?
Organisms are named by a genus and species, based on their taxonomy. Both parts of the name must be in Latin and are derived from a variety of sources.
