BIOMOLECULES AND ENZYMES

Detailed explanation-1: -The four main groups of biologically important organic compounds are carbohydrates, lipids, proteins and nucleic acids.

Detailed explanation-2: -Examples of organic molecules are hydrocarbons, aliphatic compounds, aromatic and alicyclic compounds, polymers, biomolecules, and buckyballs.

Detailed explanation-3: -Our bodies are composed mostly of water, H2O, and it is necessary for us to survive. However, water is an example of an inorganic compound because it does not contain carbon and it was not formed by a living organism.

Detailed explanation-4: -Organic molecules contain carbon; inorganic compounds do not. Carbon oxides and carbonates are exceptions; they contain carbon but are considered inorganic because they do not contain hydrogen. The atoms of an organic molecule are typically organized around chains of carbon atoms.
