- Microbiology
- Biochemistry
- Physiology
## Fundamental Concepts
### 1. Cell Theory
- All living things are composed of cells
- Cells are the basic unit of structure and function in living things
- All cells come from pre-existing cells
### 2. Central Dogma of Molecular Biology
DNA → RNA → Protein

### 5. Metabolism
Sum of all chemical reactions in an organism
## Important Definitions
- **Organism**: Any living thing
- **Ecosystem**: Community of living organisms and their environment
- **Gene**: Unit of heredity
- **Protein**: Large, complex molecules essential for life functions
- **Photosynthesis**: Process by which plants use sunlight to produce energy
- **Respiration**: Process of breaking down nutrients to release energy
## Basic Chemical Equations
1. Photosynthesis:
6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂
2. Cellular Respiration:
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy (ATP)
