BIOMOLECULES AND ENZYMES

Detailed explanation-1: -All living organisms contain organic compounds such as sugars, proteins and fats. Inorganic compounds that are important for living organisms include water, oxygen, carbon dioxide and minerals in the form of salts. Every living organism contains complex chemical compounds: or, more commonly, organic compounds.

Detailed explanation-2: -Living organisms contain inorganic compounds (mainly water and salts; see Appendix A) and organic molecules. 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.

Detailed explanation-3: -Among the numerous types of organic compounds, four major categories are found in all living things: carbohydrates, lipids, proteins, and nucleic acids. Almost all organisms use carbohydrates as sources of energy. In addition, some carbohydrates serve as structural materials.

Detailed explanation-4: -Explanation: Carbon and Hydrogen can be used in the formation of both organic and inorganic molecules. Hydrogen forms an organic compound when bonded with only hydrogen and an inorganic compound when bonded with any other element.

Detailed explanation-5: -Although about 19 million known carbon compounds have been found in organic chemistry, inorganic chemistry contains only about 500, 000 known compounds.
