| ATP | Adenosine Triphosphate |
| Metabolic pathway | Describes the process molecules go through to become a specific product. |
| Catabolic Pathways | Degrade or breakdown molecules |
| Anabolic Pathways | Consume energy to build complicated molecules from smaller ones |
| Release Energy | Catabolic reactions |
| Require Energy | Anabolic reactions |
| Energy | Can be described as the ability to cause change |
| Work | The amount of energy transferred from one system to another |
| Kinetic Energy | Energy associated with motion |
| Potential Energy | Energy matter possess because of its location or structure |
| Chemical Energy | Biologists use this term to describe potential energy from biochemical reactions |
| Sunlight | Where most of the Earth's biochemical energy originates |
| Photosynthesis | Process of converting light energy into chemical energy |
| Food chain | How energy is dispersed in an ecosystem |
| Thermodynamics | Study of energy transformationin matter |
| First law of thermodynamics | : Energy can be transferred and transformed but not created or destroyed. |
| Second law of thermodynamics | Every energy transfer or transformation increases the entropy of the universe. |
| Entropy | A quantity used to measure the disorder of the universe. |
| Heat | The way most living organisms increase entropy |
| Example of Biologically created order | Cells create ordered structure from less organized starting materials |
| Example of Biologically created disorder | Cells also take in organized forms of matter and energy and replaces them with less ordered forms |
