#Biochemistry

The standard reduction potentials (E'°) for the following half reactions are given.

Fumarate + 2H+ + 2e– -> succinate E'° = +0.031 V

FAD + 2H+ + 2e– -> FADH2 E'° = –0.219 V

If you mixed succinate, fumarate, FAD, and FADH2 together, all at l M concentrations and in the presence of succinate dehydrogenase, which of the following would happen initially?

#Biochemistry

E'° of the NAD+/NADH half reaction is –0.32 V.  The E'° of the oxaloacetate/malate half reaction is –0.175 V.  When the concentrations of NAD+, NADH, oxaloacetate, and malate are all 10–5 M, the “spontaneous” reaction is:
