## Key Concepts
- **Protein Folding**: Energy landscapes determine folding pathways
- **Membrane Fluidity**: Fluid mosaic model describes lipid bilayers
- **Brownian Motion**: Random thermal fluctuations affect molecular dynamics
- **Michaelis-Menten Kinetics**: v = V_max [S]/(K_m + [S]) for enzyme rates
- **Nernst Potential**: E = (RT/zF) ln([out]/[in]) for ion equilibrium
- **Hookean Springs**: F = -kx models molecular bond stretching
