2.1 Molecules to Metabolism

1. Nature of Science

   • Falsification of theories
     • Artificial synthesis of urea helped to falsify vitalism

2. Metabolism is the web of all the enzyme-catalysed reactions in a cell or organism

   • Catabolism
     • Breakdown by hydrolysis of macromolecules into monomers
   • Anabolism
     • Synthesis of macromolecules from monomers by condensation

3. Carbon atoms can form four covalent bonds allowing a diversity of stable compounds to exist
