WebEnzymatic action can aid this process. The enzyme-substrate complex can lower the activation energy by contorting substrate molecules in such a way as to facilitate bond-breaking, helping to reach the transition state. Finally, enzymes can also lower activation energies by taking part in the chemical reaction itself. WebDec 3, 2014 · An enzyme can act in several ways to lower Ea. It does this by forming an enzyme-substrate (ES) complex. 1. The enzyme may hold the substrates in such a way as to distort the substrate bonds closer to their … WebSome of the amino acids in an enzyme's active site play a direct role in lowering the activation energy of the given reaction B. Enzymes function primarily by lowering the activation energy of a reaction in order to speed up the rate of the reaction. C.
