Many proteins are enzymes (they catalyze reactions). Thus, it is necessary to review how reactions take place. Reduced organic compounds tend to contain stored energy in C–H bonds. As a general rule, the greater the number of C–H bonds, the greater the amount of potential energy stored in the molecule. Answer each question in the chart as it relates to the two reactions shown at the top. Be sure to be prepared to explain the reasoning behind your answers. Reaction...
