To calculate:
The change of standard free energy for the given reaction.
Introduction:
Succinate dehydrogenase is also known as SQR succinate Q reductase is seen in the cells of bacteria as a complex enzyme. It is also found in the eukaryotes in the membrane of inner mitochondria. Thus enzyme takes part in the electron transport chain and citric acid cycle.

Glu, Lys, Leu, Phe, Met, and Ser. Treatment of P1 with phenyl isothiocyanate yielded a PTH derivative of phenylalanine and a peptide (P2). Treatment of P1 with cyanogenbromide gave an acidic tetrapeptide (P3) and a dipeptide (P4).Treatment of P2 with 1-fluoro-2,4-dinitrobenzene, followed by complete hydrolysis, yields N-2,4-dinitrophenyl-Glu.
