| Photosynthesis | Process that converts light energy to chemical energy |
| Respiration | Process that releases energy by breaking down food molecules |
| Mitochondria | Organelle in which respiration takes place; found in plants AND animals |
| Chloroplast | Organelle in which photosynthesis takes place; found only in plants |
| Glucose | Molecule in which chemical energy from photosynthesis is stored |
| Autotroph | Organisms that make their own food |
| Heterotroph | Organisms that cannot make their own food |
| ATP | Universal energy "currency"; like a rechargeable battery |
| Sun | Source of light energy |
| Fermentation | Anaerobic process following glycolysis; very energy inefficient |
| Glycolysis | Initial step in the breakdown of glucose from food |
| Citric Acid Cycle | Aerobic process following glycolysis; very energy efficient |
| Anaerobic | WITHOUT oxygen |
| Aerobic | WITH oxygen |
