| activation energy |
The activation energy in chemistry is the energy needed by a system to initiate a particular process. Activation energy is often used to denote the minimum energy needed for a specific chemical reaction to occur. For a reaction to occur between two colliding molecules, they must collide in the correct orientation, and possess a certain, minimum, amount of energy. As the molecules approach each other, their electron clouds repel each other. ...

| active site |
活性部位, That portion of a protein, usually an enzyme, whose structural integrity is required for function (eg, the substrate binding site of an enzyme). Enzymes may have more than one active site and so catalyse more than one reaction. Competitive inhibitors of an enzyme reaction bind reveribly to the active site and reduce its availability for normal substrate.
