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.

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...
