Homework Answers
c) The CAC would slow down/stop (Option C is correct)
Note- This will happen as Increase in the ratio
of [NADH]/[NAD+] will actually inhibit the
CAC via mass action at all the
3 stages that involve the NAD reduction and the high amounts of
[NADH] will cause the shifting of the equilibrium towards
[NAD+]

1. Select the TRUE statement about the citric acid cycle. A. Isocitrate dehydrogenase is a multienzyme complex that is very similar to the pyruvate dehydrogenase complex B. The two decarboxylation steps occur right after each other, first via oxidative alpha- decarboxylation, then via oxidative beta- decarboxylation. C. In one turn of the cycle, the two carbons that enter the cycle as acetyl CoA are the same two carbons that are released as CO2. D. A flavin containing dehydrogenase enzymes oxidizes...

Calcium is an important regulator of the citric acid cycle. Calcium is transported across the mitochondrial inner membrane by a Ca2+ uniporter that is driven by the negative potential inside the matrix. Part A Assuming a membrane potential across the inner membrane of 179 mV (inside negative), calculate the ratio of the [Ca2+] in the matrix to that in the cytoplasm ([Ca2+]m/[Ca2+]c) that would exist at equilibrium (i.e., ΔG=0). Part B Cytoplasmic [Ca2+] is on the order of 10−7M in...

In 1937 Hans Krebs deduced the operation of the
citric acid cycle from careful observations on the oxidation of
carbon compounds in minced preparations of pigeon flight muscle.
(Pigeon breast is a rich source of mitochondria, but the function
of mitochondria was unknown at the time.) The consumption of O2 and
the production of CO2 were monitored with a manometer, which
measure changes in volume of a closed system at a constant pressure
and temperature. Standard chemical methods were used...
