In addition to the purchase price of a property in France, and the various expenses, commissions, and taxes that that purchase entails, there is a further series of outlays that will arise out of your purchase.
When an enzyme binds its substrate, it forms an enzyme-substrate complex. This complex lowers the activation energy of the reaction and promotes its rapid progression by providing certain ions or chemical groups that actually form covalent bonds with molecules as a necessary step of the reaction process.
The enzyme changes shape upon binding to the substrate. The active site has a shape complementary to that of the substrate only after the substrate is bound. In an enzyme catalyzed reaction, the rate of enzyme catalyzed reaction varies with the concentration of the substrate, as shown in the figure.
