Carbon Cycle
The cycle through which carbon atoms circulate in the Earth's ecosystems, including processes such as photosynthesis, respiration, and combustion.
Human body composition
The human body is made up of approximately 96.2% CHO (carbon, hydrogen, oxygen) and 3.2% nitrogen.
Photosynthesis formula
6CO2 + 6H2O — C6H12O6 + 6O2
removes CO2 from the atmosphere
Cellular respiration
C6H12O6 + 6O2 — 6CO2 + 6H2O + Energy
releases CO2 back into the atmosphere, completing the cycle
Combustion
The process of burning fossil fuels such as coal, oil, and natural gas, which releases carbon dioxide into the atmosphere.
Nucleic acids
Biomolecules essential for all known forms of life, made up of nucleotide chains; include DNA and RNA.
Erosion
The process by which natural forces like wind, water, or ice wear away rocks and soil, contributing to the carbon cycle.
Valence electrons
Electrons in the outer shell of an atom that are involved in forming bonds with other atoms; carbon has four valence electrons.
The significance of carbon
Carbon serves as the backbone of organic compounds due to its ability to form four stable covalent bonds with other atoms.
What are the organic compounds
Carbohydrates, lipids, proteins, nucletic acids
importance of carbon
Its the back bone of organic compounds
carbon atom
6 protons, 2 electrons(first shell), 4 electrons (second shell), 4 bonds with other molecules
Carbon in nature
makes up about 416 ppm (.0416) of the atmosphere as gas (CO2) in oceans as dissolved CO2 and in rocks
