WebConsider the reaction pathway graph below. mc024-1.jpg Which inference is supported by evidence in the graph? The energy required to make the activated complex is greater than A + C. This is an exothermic reaction where the total release of energy equals A + C. The products need more energy to form than the reactants as shown by F. WebEnzymes and activation energy. A substance that speeds up a chemical reaction—without being a reactant—is called a catalyst. The catalysts for biochemical reactions that happen in living organisms are called enzymes. Enzymes are usually proteins, though some ribonucleic acid (RNA) molecules act as enzymes too.
