What are macromolecules of life?

Answer 1

Polymers are large molecules composed of many similar smaller molecules linked together. The individual smaller molecules are called monomers. When small organic molecules are joined together, giant molecules are produced. These giant molecules are known as macromolecules.

Answer 2

The macromolecules of life include proteins, lipids, nucleic acids, and carbohydrates. These 4 groups of molecules contribute the basic building blocks of life. Protein-->almost an endless amount of things in the body are made of protein, contain proteins, or simply are proteins. Enzymes are proteins that catalyse reactions in the body. Skin and hair contain collagen, a structural protein. Lipids--> without lipids, our cells would fall apart and we would fail to have a form or shape about us. A wonderful little molecule called a phospholipid gives our cells a "fluid" boundary in which to float in our extracellular fluid. Nucleic acids--> these are probably the most important macromolecule. Nucleic acids are the building blocks of DNA (deoxyribonucleic acid), the blueprint of life. They are "monomers" that bind together into the "polymer" DNA. Carbohydrates--> some known these guys as "sugars", but really they are more than that. Carbohydrates are used in a little process we like to call "cellular respiration". Without cellular respiration, our cells would die, due to lack of energy (no ATP production). This is only a small dent in the great importance of the macromolecules.

Answer 3

Macromolecules of life are large, complex molecules essential for various biological functions. The four main categories are proteins, carbohydrates, lipids, and nucleic acids. These macromolecules play important roles in processes such as structure, energy storage, communication, and genetic information.
