| Term | Definition |
|---|---|
| Energy | Ability to do work or bring about a change |
| Kinetic Energy | Energy of motion |
| Potential Energy | Stored energy |
| Mechanical energy | has potential for a reaction, though at present is in a stored form |
| Chemical Energy | released as a result of a chemical reaction, as in the metabolism of food |
| First law (law of conservation of energy) | cannot be created or destroyed, but it can be changed from one form to another |
| Second law of Energy | cannot be changed from one form to another without a loss of usable energy |
| Reactant | original chemical |
| Product | chemical that is created when you combine two or more reactants |
| Exergonic Reactions | energy is released |
| Endergonic Reactions | requires an input of energy to occur |
| ATP (adenosine triphosphate) | High energy compound used to drive metabolic reactions |
| enzyme | protein molecules that function as organic catalysts to speed a chemical reaction |
| metabolic pathway | requires a unique and specific enzyme |
| energy of activation | The energy that must be added to cause molecules to react with one another; causes reactants to become products |
| substrate | A surface on which an organism grows or is attached |
| active site | undergoes a change in shape to accommodate the substrates |
| denatured | take away or alter the natural qualities of |
| oxidation | is the loss of electrons |
| reduction | is the gain of electrons |
