2.1. Protein structure (1, 2, 3 and quaternary)
2.2. Sculpting protein structure (modifications)
2.3. Protein folding and quality control (chaperone example)
2.4. Enzyme characteristics, reaction and energy potential
2.5. Orders of kinetic reactions
2.6. Allostery
2.7. Cooperativity

Module 3: Energy
