Therefore, one of the main functions of digestive enzymes is to increase the bioavailability of nutrients.
WebThe enzyme-substrate complex can also lower activation energy by bending substrate molecules in a way that facilitates bond-breaking, helping to reach the transition state. Finally, some enzymes lower activation energies by taking part in the chemical reaction themselves. That is, active site residues may form temporary covalent bonds with ...
