*** WHAT'S COVERED ***
1. The 4 main types of biological molecules.
* Carbohydrates, lipids, proteins, and nucleic acids.
* Their organic nature and the role of carbon bonding.
* The elements found in each type (C, H, O, N, P).
2. Monomers and polymers.
* Definitions of monomers and polymers.
* Specific examples: monosaccharides/polysaccharides, amino acids/polypeptides, nucleotides/polynucleotides.
* The concept of polymerisation.
* Why lipids don't fit the strict definition of polymers.
3. Condensation and hydrolysis reactions.
* How polymers are synthesised via condensation (water removed).
* How polymers are broken down via hydrolysis (water added).
* The role of energy (ATP) and water in these reactions.
