| 7868760392 | endergonic | A chemical reaction that requires the input of energy in order to proceed. | 2 | |
| 7868761872 | exergonic | Chemical reactions that release energy | 3 | |
| 7868762772 | ATP-coupled | Endergonic reaction that requires ATP to proceed (ie - building sucrose) | 4 | |
| 7868768222 | First Law of Thermodynamics | Energy is neither created nor destroyed, but may be converted from one form to another | 5 | |
| 7868768898 | Second Law of Thermodynamics | The entropy (disorder) of the universe (or system) tends to increase. | 6 | |
| 7868771777 | Products are more complex | in an endergonic reaction | 7 | |
| 7868772382 | Products are less complex | in an exergonic reaction | 8 | |
| 7868774663 | Gibbs Free Energy | ΔG = ΔH - TΔS | 9 | |
| 7868775179 | free energy | energy that is available to do work | 10 | |
| 7868776008 | entropy | A measure of disorder or randomness. | 11 | |
| 7868776009 | enthalpy | total energy | 12 | |
| 7868778436 | enzyme | A type of protein that speeds up a chemical reaction in a living thing | 13 | |
| 7868779336 | activation energy | Energy needed to get a reaction started | 14 | |
| 7868782842 | active site | Region of an enzyme into which a particular substrate fits. | 15 | |
| 7868784569 | feedback inhibition | process in which the product or result stops or limits the process | 16 | |
| 7868785481 | competitive inhibitor | competes with substrate for active site | 17 | |
| 7868786101 | non-competitive inhibitor | an inhibitor that binds to an enzyme at an allosteric site. | 18 | |
| 7868787576 | allosteric inhibition | two active sites, one for a substrate and one for an inhibitor | 19 | |
| 7868795394 | metabolism | the combination of chemical reactions through which an organism builds up or breaks down materials | 20 | |
| 7868798853 | open system | A system in which matter can enter from or escape to the surroundings. | 21 | |
| 7868800995 | spontaneous | happens without an input of energy (exergonic) | 22 | |
| 7868802398 | non-spontaneous | cannot happen without energy input (endergonic) | 23 | |
| 7868813123 | co-factor | inorganic compound required for the proper functioning of an enzyme | 24 | |
| 7868820879 | induced fit model | enzyme model where the substrate induces the enzyme to alter its shape slightly so it fits better | 25 | |
| 7868823338 | allosteric activation | occurs when an "activator" binds with the enzyme and increases its turnover rate | 26 | |
| 7868829705 | co-enzyme | a small molecule (not a protein but sometimes a vitamin) essential for the activity of some enzymes | 27 | |
