Interpretation Introduction
Interpretation:
Among the given three families of curves, the family of three curves that is expected to be obtained is to be stated.
Concept introduction:
The Michaelis-Menten equation relates the concentration of substrate with the velocity of the reaction. A constant which expresses the substrate’s concentration if the velocity of reaction equals to the half of the maximum velocity of the reaction is known as Michaelis-Menten constant. It is denoted by

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?
