Thank you for the opportunity to help you with your question!
1) carbon, nitrogen,hydrogen,oxygen,phosphorous and sulfur.
phosphorous = 1%
sulfur +other elements= 2%
4 COMMON COMPLEX MOLECULES:
* Nucleic acid
IMPORTANCE OF MACROMOLECULES
ProteinsProteins are probably the most versatile of all the organic molecules, making up many structures and executing various functions within organisms. Building blocks called amino acids make up proteins.
they are the instant source of energy for living organisms. All the living organisms require carbohydrates for their body functions to be performed. they store carbohydrates in the form of starch (plants) and glycogen(animals).
Lipids, perhaps better known as fats, come in different forms in your body and contain the most energy of all the organic compounds. When your body burns lipids for fuel, you get more energy than if you burned the other organic molecules. In your body, fats perform many functions, taking the form of phospholipids and cholesterol, both important components of cell membranes; waxes that provide plants and animals with a protective layer; hormones that signal different functions in your body; vitamins that aid in different cell functions; and steroids, which are important in a number of physiological processes. Fats from animals tend to be more viscous than fats from plants.
Nucleic AcidsThe nucleic acids are DNA and RNA, or deoxyribonucleic acid and ribonucleic acid, respectively. They make the proteins that are present in almost every structure and perform almost every function in your body.
3) we can get these macromolecules through diet except the nucleic acid because they are also hereditary material and transfers from generation to generation through reproduction.
