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.

Expert Solution

Explanation of Solution

The electron acceptor is O2 and the electron donor is succinate which is determined from the half reactions:

Fumarate+2H++2e−→Succinate+(E0'=+0.031V)

12O2+2H++2e−→H2O,(E0'=+0.816V)

The free change of energy for the reaction is calculated by determining the change of the standard potential:

ΔE0'=acceptorΔE0'−donorΔE0'

=+0.816 V−(0.031 V)=+0.785 V

ΔG0'=−nFΔE0'n=2F=96,485 kJ/Vmol

=−2(96.485 kJ/V.mol)(0.785 V)=−151.5 kJ/mol

Expert Solution

Explanation of Solution

From the given we have,

G=−151.3 kJ/mol for 2 ATP

So with 70% efficiency,

−151.3 kJ/mol×0.70=−106.1 kJ/mol

For 1 ATP,

53.1 kJ/mol

With the equation,

ΔG=ΔG0+RTln(ATP)(ADP)(Pi)

(ATP)(ADP)=(Pi)×eΔG−ΔG 0'RT

=(1 mM)×e (53.05−30.5) (8.314× 10 −3 )(298)=8.89

The ratio of ATP and ADP maximum for the phosphorylation oxidative occurring at Pi =1 mM is 8.89.
