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.
When the substrates and enzymes are within close proximity the substrates bind to the active sites which is a specially shaped binding site of the enzyme that fits around the substrate. It is here where catalysis occurs and facilitates the reaction, taking in less activation energy than an unaided reaction.
