| 94065189 | Metabolic Pathways | A series of chemical reactions that either builds a complex molecule or breaks down a complex molecule into simpler compounds | |
| 94065190 | Catabolic Pathways | A metabolic pathway that releases energy by breaking down complex molecules to simpler compounds | |
| 94065191 | Anabolic Pathways | A metabolic pathway that synthesizes a complex molecule from simpler compounds | |
| 94065192 | Kinetic Energy | The energy of motion, which is directly related to the speed of that motion. Moving matter does work by imparting motion to other matter | |
| 94065193 | Thermal Energy | The totall amount of kinetic energy due to molecular motion in a body of matter. Heat is energy in its most random form | |
| 94065194 | Potential Energy | The energy stored by matter as a result of its location or spatial arrangement | |
| 94065195 | Chemical Energy | Energy stored in the chemical bonds of molecules; a form of potential energy | |
| 94065196 | First Law of Thermodynamics | The principle of conservation of energy. Energy can be transferred and transformed, but it cannot be created or destroyed | |
| 94065197 | Entropy | A quantitative measure of disorder of randomness, symbolized by 'S' | |
| 94065198 | Second Law of Thermodynamics | The principle wheerby every energy transfer or transformation increases the entropy of the universe. Ordered forms of energy are at least partly converted to heat, and in spontaneous reactions, the free energy of the system also decreases | |
| 94065199 | Exergonic Reaction | A spontaneous chemical reaction, in which there is a net release of free energy | |
| 94065200 | Endergonic Reaction | A nonspontaneous chemical reaction, in which free energy is absorbed from the surroundings | |
| 94065201 | Energy Coupling | In cellular metabolism, the use of energy released from an exergonic reaction to drive an endergonic reaction | |
| 94065202 | ATP | A cluster of several membrane proteins found in the mitochondrial crista tat function in chemiosmosis with adjacent electron trasport chains, using the energy of a hydrogen ion concentration gradient to make ATP. ATP synthases provide a port through which hydrogen ions diffuse into the matrix of a mitochondrion. | |
| 94065203 | Phosphorylated | Referring to a molecule that has been the recipient of a phosphate group | |
| 94065204 | Catalyst | A chemical agent that changes the rate of a reaction without being consumed by the reraction | |
| 94065205 | Enzyme | A protein serving as a catalyst, a chemical agent that changes the rate of a reaction without being consumed by the reaction | |
| 94065206 | Activation Energy | The amount of energy that reactants must absorb before a chemical reaction will start | |
| 94065207 | Substrate | The reactant on which an enzyme works | |
| 94065208 | Enzyme-Substrate Complex | A temporary complex formed when an enzyme binds to its substrate molecule(s) | |
| 94065209 | Active Site | The specific portion of an enzyme that attaches to the substrate by means of weak chemical bonds | |
| 94065210 | Induced Fit | The change inshape of the active site of an enzyme so that it binds more snugly to the substrate, induced by entry of the substrate | |
| 94065211 | Cofactor | Any nonprotein molecule or ion that is required for the proper funcitoning of an enzyme. They can be permanently bound to the active site or may bind loosely with the substrate during catalysis | |
| 94065212 | Coenzyme | An organic molecule serving as a cofactor. Most vitamins funciton as ... in important metabolic reactions | |
| 94065213 | Competitive Inhibitor | A substance that reduces the activity of an enzyme by entering the active site in place of the substrate whose structure it mimics | |
| 94065214 | Noncompetitive Inhibitor | A substance that reduces the activity of an enzyme by binding to a location remote from the active site, changing its conformation so that it no longer binds to the substrate | |
| 94065215 | Allosteric Regulation | The binding of a molecule to a protein that affects the function of the protein at a different site | |
| 94065216 | Cooperativity | An interaction of the constituent subunits of a protein whereby a conformational change in one subunitt is transmitted to all the others | |
| 94065217 | Feedback Inhibition | A method of metabolic control in which the end product of a metabolic pathway acts as an ingibitor of an enzyme within that pathway | |
| 94067716 | Metabolism | The emergent property of life that arises from interactions between molecules within the orderly environmentof the cell |
