Consider the malate dehydrogenase reaction from the citric acid cycle. given the following concentrations, calculate the free energy change for this reaction at 37.0 °c (310 k). δg°\' for the reaction is 29.7 kj/mol. assume that the reaction occurs at ph 7. [malate] = 1.13 mm [oxaloacetate] = 0.270 mm [nad ] = 390 mm [nadh] = 160 mm

Explanation:

According to the reaction,

The expression for the equilibrium constant is:-

Given:-

[malate] = 1.13 mM

[oxaloacetate] = 0.270 mM

= 390 mM

[NADH] = 160 mM

Thus,

The expression for calculation of free energy change is shown below as:-

Where, R is gas constant, 8.314 J/K.mol

T is the temperature in Kelvins

So, Given:-

T = 310 K

Thus,
