A chemical reaction that has a positive G is correctly described as, Endergonic The primary function of an enzyme or any biological catalyst is to reduce the energy of activation and increase the rate of a reaction. Altering the three-dimensional structure of an enzyme might prevent the substrate from binding the enzyme's active site. A bowl of sugar water is very stable. However, cells can rapidly break down sugar into carbon dioxide and water. What is the best explanation for this observat...
