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.
It was thought that the substrate exactly fitted into the active site of the enzyme molecule like a key fitting into a lock (the now discredited âlock and keyâ theory). This explained why an enzyme would only work on one substrate (specificity), but failed to explain why the reaction happened.
