How does an enzyme affect activation energy

WebMolecules that increase the activity of an enzyme are called activators, while molecules that decrease the activity of an enzyme are called inhibitors. There are many kinds of … WebJan 1, 2007 · In general, activation energies for enzyme-catalysed reactions are within the range of 25- 63 kJ mol -1. Thus, catalase is not only more efficient than inorganic catalysts such as iodide, but also an exceptionally efficient enzyme. A low value of activation energy implies high efficiency of molecular collisions to form products.

How does enzymes lower the activation energy? [Expert Review!]

WebExpert Answer 100% (20 ratings) let's have a look on the topic the enzymes and the reaction: A Substance that helps a chemical reaction to occur is a catalyst, while enzymes are special molecules that catalyst biochemical reactions. Activation energy represents the energy required … View the full answer Transcribed image text: WebEnzymes do affect the activation energy. The activation energy is the difference in free energy between the substrate and the transition state.
