What is the benefit/advantage of having two divergent
paths for electron flow through complex III? Why is the Q cycle
better than a single QH2 donating its two electrons, one
at a time, along the same path to cytochrome c?
Part of the Q-cycle within Complex III of the electron transport
chain involves the transfer of a single electron from cytochrome bH
to UQ. In the next round of the cycle, another single electron from
cytochrome bH is passed to UQH·. Protons are harvested from the
matrix.

processes indicating the εo´ values
[2] (b) Write the overall net reaction
[5] (c) Calculate G°'overall for this process at 25°C
In a two-dimensional vortex flow, the fluid flows in circular
paths around the center of the vortex. The magnitude of the
velocity decreases with distance from the center. The stream
function for a two-dimensional vortex centered at the origin is
ψ=ln sqrt(x^2+y^2) where the x--y plane is horizontal and x and y
are in meters. Show that continuity of the flow is satisfied and
determine the magnitude of the horizontal velocity at A, where
x=−0.2m, y=0.4m. Express your answer in...

Pentammino Complex of Cobalt(III) Chloride [Co(NH3)5Cl]Cl2,
Pentamminenitro- and Nitritro- Cobalt(III) Chloride
How does proton flow through the FO/CFO portion of the ATP synthase complex contribute to ATP synthesis in the F1/CF1 portion of the complex? What role does the amino acid asparatate play in this process?
