## Key Concepts

### Cell Membrane

**Fluid Mosaic Model**
- Phospholipid bilayer
- Membrane proteins (integral, peripheral)
- Cholesterol
- Carbohydrate chains (glycocalyx)

**Transport Mechanisms**
- Passive diffusion: Small nonpolar molecules
- Facilitated diffusion: Channels, carriers
- Active transport: Pumps, ATP-dependent
- Vesicular transport: Exocytosis, endocytosis

### Cellular Energetics

```python
# ATP synthesis overview
def cellular_respiration():
    """Main energy production pathway."""
    return {
        'glycolysis': 'Glucose → 2 Pyruvate + 2 ATP',
        'krebs_cycle': 'Acetyl-CoA → CO2 + electron carriers',
        'etc': 'O2 + electrons → H2O + 34 ATP'
    }
```

### Energy Carriers

- ATP: Primary energy currency
- NAD⁺/NADH: Electron carrier (catabolism)
- NADP⁺/NADPH: Electron carrier (anabolism)
- FAD/FADH₂: Electron carrier (mitochondria)
