The reaction depicted is the conversion of succinate to fumarate coupled with the reduction of FAD to FADH2. This reaction is catalyzed by the enzyme succinate dehydrogenase. The ?G0 of this reaction is +6 kcal/mol. Use this information to answer the following questions.
Because the ?G0 of this reaction is positive, this reaction will only occur in the cell if coupled to an exergonic reaction.
True or False
Succinate dehydrogenase will be used up during this reaction, so it must be replenished by the cell if the reaction is to continue occurring over time.
True or False
When this reaction is at equilibrium, no more molecules of succinate will be converted to fumarate.
True or False
If standard entropy (?S0) increases over the course of this reaction, then standard enthalpy (?H0) could decrease.
True or False
Which of the following statements accurately describes the effect of succinate dehydrogenase on this reaction?
1. Succinate dehydrogenase lowers the overall ?G of this reaction, making it more favorable.
2. Succinate dehydrogenase provides the activation energy for this reaction to proceed.
3. Succinate dehydrogenase will make both the forward and reverse reactions occur at a faster rate.
4. Succinate dehydrogenase will speed up the forward reaction and slow down the reverse reaction
5. More than one of these is true.
6. None of these is true.
