(a)

Summary Introduction

To determine: The value of ∆Gꞌ˚ for the interconversion reaction of fructose 6-phosphate and glucose 6-phosphate at 25˚C.

Introduction:

The standard free-energy change for an oxidation-reduction reaction is directly proportional to the difference in standard reduction potentials of two half-cells. The formula is ∆Gꞌ˚=- ƞFEꞌ˚ and ∆Gꞌ˚=- RT ln∆Keq.

(b)

Summary Introduction

To determine: The value of ∆Gꞌ˚ for the interconversion reaction of “fructose 6-phosphate” and “glucose 6-phosphate” if the concentration of fructose 6-phospharte is 1.5M and that of glucose-6 phosphate is 0.5M.

Introduction:

The standard free-energy change for an oxidation-reduction reaction is directly proportional to the difference in standard reduction potentials of two half-cells. The formula is ∆Gꞌ˚=- ƞFEꞌ˚ and ∆Gꞌ˚=- RTln∆Keq.

(c)

Summary Introduction

To determine: The reason behind the difference of ∆G and ∆Gꞌ˚.

Introduction:

The standard free-energy change for an oxidation-reduction reaction is directly proportional to the difference in standard reduction potentials of two half-cells. The formula is ∆Gꞌ˚= -ƞFEꞌ˚ and ∆Gꞌ˚= - RT ln ∆Keq.

Pyruvate is accepted into the TCA cycle by a “feeder” reaction using the pyruvatedehydrogenase complex, resulting in acetyl-CoA and CO2. Provide a full mechanismfor this reaction utilizing the TPP cofactor. Include the roles of all cofactors.
B- Vitamins are converted readily into important metabolic cofactors. Deficiency inany one of them has serious side effects. a. The disease beriberi results from a vitamin B 1 (Thiamine) deficiency and ischaracterized by cardiac and neurological symptoms. One key diagnostic forthis disease is an increased level of pyruvate and α-ketoglutarate in thebloodstream. How does this vitamin deficiency lead to increased serumlevels of these factors? b. What would you expect the effect on the TCA intermediates for a patientsuffering from vitamin B 5 deficiency? c. What would you expect the effect on the TCA intermediates for a patientsuffering from vitamin B 2 /B 3 deficiency?
