254073126 | Thermodynamics | branch of chemistry concerned with energy changes | |
254073127 | Kinetic energy | energy of motion | |
254073128 | Potential energy | stored energy based on location, position or charge | |
254073129 | Free energy | energy available to do work | |
254073130 | Endergonic reactions | any reaction that requires an input or is energy storing | |
254073131 | Exergonic reactions | any reaction that proceeds spontaneously and releases energy | |
254073132 | Activation energy | energy required to initiate a reaction | |
254073133 | Catalyst | molecule or compound that lowers activation energy | |
254073134 | ATP | energy currency of living organisms | |
254073135 | Substrate | the molecules that will undergo the reaction | |
254073136 | Active site | place where enzyme binds, critical location | |
254073137 | Induced fit | the concept that during the formation of the enzyme-substrate complex there is a slight change in enzyme shape to catalyze the reaction | |
254073138 | Multienzyme complexes | several enzymes catalyzing reactions are associated without covalent bonded assemblies | |
254073139 | Ribozymes | RNA molecules that are capable of lowering activation energy | |
254073140 | Competitive inhibitor | decreased rate of reaction based on molecule "attaching" at the active site | |
254073141 | Noncompetitive inhibitor | decreased rate o reaction based on molecule "attaching" away from the active site | |
254073142 | Allosteric enzymes | enzymes with two different "shapes", one that increases the rate of reaction and one that decreases rate | |
254073143 | Anabolism | chemical reactions that expend energy to build molecules | |
254073144 | Catabolism | chemical reactions that release energy breaking down molecules | |
254073145 | Feedback inhibition | regulation of a biochemical pathway by an end-product of that pathway |
