are humans made of carbon?

Almost 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium. All 11 are necessary for life.

Yes, all things are made of atoms, and all atoms are made of the same three basic particles - protons, neutrons, and electrons. ... For instance hydrogen has one proton, carbon has six. The difference in the number of protons and neutrons in atoms account for many of the different properties of elements.

Carbohydrates and lipids are made of only carbon, hydrogen, and oxygen (CHO). Proteins are made of carbon, hydrogen, oxygen, and nitrogen (CHON). Nucleic acids such as DNA and RNA contain carbon, hydrogen, oxygen, nitrogen, and phosphorus (CHON P).

The mass of a tree is primarily carbon. The carbon comes from carbon dioxide used during photosynthesis. During photosynthesis, plants convert the sun's energy into chemical energy which is captured within the bonds of carbon molecules built from atmospheric carbon dioxide and water.

The raw materials are water, carbon dioxide, oxygen, glucose, and energy.

Carbon is one of the most important elements to life on planet Earth. It forms more compounds than any other element and forms the basis to all plant and animal life.

Trees use the carbon from carbon dioxide to make sugar molecules. Woody tissue and bark of trees comprise most of a tree's biomass. Wood and bark is made of cellulose, which contains carbon, hydrogen and oxygen atoms.

Carbon Dioxide Emissions: Human Sources Human activities such as the burning of oil, coal and gas, as well as deforestation are the primary cause of the increased carbon dioxide concentrations in the atmosphere.

Atmospheric carbon dioxide comes from two primary sources—natural and human activities. Natural sources of carbon dioxide include most animals, which exhale carbon dioxide as a waste product.

Humans are moving more carbon into the atmosphere from other parts of the Earth system. More carbon is moving to the atmosphere when fossil fuels, like coal and oil, are burned. More carbon is moving to the atmosphere as humans get rid of forests by burning the trees.

The short answer is… yes! Carbon atoms form the “backbone” of almost all the important biological molecules floating around in our bodies (except water, of course.) Therefore, when we say life is “carbon based,” we mean that our skin, hair and cells are all made out of molecules that contain large amounts of carbon.

In comparison, human emissions of carbon to the atmosphere are on the order of 1015 grams, whereas the fast carbon cycle moves 1016 to 1017 grams of carbon per year. ... The movement of carbon from the atmosphere to the lithosphere (rocks) begins with rain.

Cells are made of proteins, which are a type of molecule, and water, which is another molecule, and other things which are all made of molecules. ... Proteins are made of carbon, hydrogen, oxygen, and other elements. So we know that the molecules that make up the cells of the body are made of atoms.

Most biomolecules are organic compounds, and just four elements—oxygen, carbon, hydrogen, and nitrogen—make up 96% of the human body's mass.

Coal burned in power stations contains carbon which combines with oxygen in the atmosphere to form carbon dioxide. The man-made (or anthropogenic) component of the greenhouse effect is caused by man's activities that emit greenhouse gases to the atmosphere. The most important of these is the burning of fossil fuels.

On an elemental level, human urine contains 6.87 g/L carbon, 8.12 g/L nitrogen, 8.25 g/L oxygen, and 1.51 g/L hydrogen. The exact proportions vary with individuals and with factors such as diet and health. In healthy persons, urine contains very little protein and an excess is suggestive of illness.

It has been estimated that the solid earth as a whole contains 730 ppm of carbon, with 2000 ppm in the core and 120 ppm in the combined mantle and crust. Since the mass of the earth is 5.972×1024 kg, this would imply 4360 million gigatonnes of carbon.
