Unformatted text preview: D) All of the above. E) None of the above. 5 Enzymes accelerate the rate of a chemical reaction by __________________ the free energy of activation of the reaction. 6 The difference between the standard-state free energy, G, and the biochemical standard-state free energy is that G refers to the standard free-energy change at ________. 7 Most known enzymes are proteins; however, some ___________ molecules have been shown to possess catalytic activity. 8 Organic cofactors are referred to as __________________. 9 A reaction can occur spontaneously only if G is __________________. 10 When G for a system is zero, the system is at ______________________. 11 How is the substrate bound to the active site? 12 In an enzymatic reaction in a test tube, the reaction will eventually reach equilibrium. Why does this not happen in living organisms?...
