Question
The last reaction of the citric acid cycle is the conversion of malate to oxaloacetate, catalyzed by malate
dehydrogenase. The standard reduction potential for oxaloacetate malate is -0.166 V.
1 What is the difference in the standard reduction potential for the whole redoxreaction and what is the
standard free energy change for the full reaction? To calculate this, look up the standard reduction potential
for the correct redox-active cofactor in the lecture notes (table 15-1). Faraday's constant F = 96485 J* mol
Note: In an exam, you will be gven the standard reduction potential and the constants.
O A) Ae" = -0.481 V
AG= +92.82 kj/mol
Ae=-0.481 V
O B)
AG = +4.52 kl/mol
C Ae = -0.149 V
AG = +28.75 kl/mol
D) Ae = -0.149 V
AG=28.75 kl/mol
O E) Ac = +0.149 V
AG- -28.75 kl/mol
