WebA more complete way of showing the effects of enzymes: Enzymes bind to substrates, so G(ES) < G(E+S). However, if all they did was to bind, then Ea =ΔG(ES*) for the reaction would not be reduced. So when they bind the substrate, they stress It in some way, raising G(ES) for part of the substrate and reducing ΔG(ES*)(=Ea). naeyc formsWebEnzymes let chemical reactions in the body happen millions of times faster than without the enzyme.
