1. The chemistry of life is carried out and coordinated primarily by the action of small molecules.
2. Carbon-based compounds make up the vast majority of molecules found in cells.
3. The chemical reactions in living systems are loosely regulated, allowing for a wide range of products and more rapid evolution.

1. The chemistry of life is carried out and coordinated primarily by the action of macromolecules, primarily, enzymes, which average between 40 and 50 kDa in size.

3. The chemical reactions in living systems are strictly regulated, allowing for a efficient use of the resources in order to grow, develop and reproduce.
