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.
In biology and biochemistry, the reactant in an enzyme reaction is known instead as the substrate. You mustn't take this picture of the way a substrate fits into its enzyme too literally. What is just as important as the physical shape of the substrate are the bonds which it can form with the enzyme. Enzymes are protein molecules-long chains of amino acid residues.
