2.1 Molecules to metabolism:Intro to Molecular Biology

Understanding that:

- Molecular biology explains living processes in terms of the chemical substances involved
- carbon atome can form four covalent bonds allowing a diversity of stable compounds to exist
-life is based on carbon compounds including carbohydrates, lipids, proteins and nucleic acids
-metabolism is the web of all the enzyme-catalysed reactions in a cell or organism
- anabolism is the synthesis of complex molecules from simpler molecules including the formation of macromolecules from monomers by condensation reactions
-catabolism is the breakdown of complex molecules into simpler molecules including the hydrolysis of macromolecules into monomers
