All of the major components of the light reactions, including the pigment molecules
clustered in photosystems I and II, are located in the thylakoid membrane. What is the advantage of
having these components confined to the same membrane rather than dissolved in the stroma or the
cytosol/cytoplasm? Explain your argument. (up to 5 points)

Answer:

Having the light reaction components in close proximity speeds up the process. Electrons move from one protein to the next in sequence. If the proteins had to 'swim' around to find the next part of the electron transport chain, then the ATP would form at a much slower, inefficient rate.
