Chapter 20, Problem 44P
Interpretation Introduction

Interpretation:

Efficiency of photosynthesis should be estimated.

Concept introduction:

Autotrophs can produce glucose via Calvin cycle with the use of carbon dioxide and water and using photon energy by sunlight. Three molecules of ATP and 2 molecules of NADPH are consumed to produce a hexose from CO2.

The mitochondrial ATP synthase has 10 copies of the F0 subunit “c”, and the [H ] in the mitochondrial inner membrane space (IMS) is 6.31 x 10-8 M and the [H + ] in the matrix is 3.16 x 10-9 M. Calculate the minimum membrane potential (∆Ψ) necessary to make ATP synthesis thermodynamically favorable. [Assume ∆G' ofphosphate hydrolysis of ATP is - 45 kJ/mol.]
B- Vitamins are converted readily into important metabolic cofactors. Deficiency in any one of them has serious side effects. a. The disease beriberi results from a vitamin B 1 (Thiamine) deficiency and is characterized by cardiac and neurological symptoms. One key diagnostic for this disease is an increased level of pyruvate and α-ketoglutarate in the bloodstream. 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 patient suffering 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?
Pyruvate is accepted into the TCA cycle by a “feeder” reaction using the pyruvate dehydrogenase complex, resulting in acetyl-CoA and CO2. Provide a full mechanism for this reaction utilizing the TPP cofactor. Include the roles of all cofactors.
