WebChemical Substrate Definition. A substrate is a molecule that an enzyme reacts with. The enzyme’s active site, or the location where weak bonds between the two molecules can form, is loaded with a substrate. An enzyme substrate complex is formed, and the enzyme’s pressures on the substrate drive it to react and become the planned reaction ... WebAlso, in a process called cooperativity, the substrate itself can serve as an allosteric activator: when it binds to one active site, the activity of the other active sites goes up. 3 … b7バルキー 価格
