7. What role does water play in the process of building macromolecules Why is it such an
important component of life
Extension:
The Monomers of Macromolecules
All key components of every living cell are made of macromolecules. The four kinds of
macromolecules are lipids, carbohydrates, nucleic acids, and proteins. Most macromolecules
are polymers constructed of many organic molecules called monomers.
These molecules represent one level of basic building blocks of life. These monomers, or single
molecules, can be joined with other monomers to form larger units (polymers). They can be
divided into four groups:
1. carbohydrates (sugars for energy and structure)
2. lipids (fats for membranes and energy storage)
3. nucleic acids (information bearers)
4. proteins (the molecular machines of the cells).
