On the right is a schematic showing the structure of complex V (ATP Synthase). The various subunits are labeled. 1. List the specific subunits in the complex that rotate as protons flow through the complex (select from: a, b2, c, a, b, g, d, 2. Rotation occurs in 1200 steps. Briefly explain why this is consistent with the bind-and-change mechanism that produces ATP. In your answer, make sure to indicate the number of active sites in the complex and how rotation alters their ability to promote catalysis. 3. Draw a reaction coordinate diagram describing the different steps of ATP synthase catalysis, comparing the relative free energy of each state. What is the rate-limiting step in ATP synthase catalysis in the direction of ATP synthesis? 4. What conformational state is stabilized by g in ATP synthase? Why might achieving this state require energy input from the PMF? a B a B Y b Inner membrane ccccc
