The final question is the toughest. You noticed that LH1-, LH2+, RC+ was much more affected by the light level than LH1+, LH2-, RC+. In other words, it hurts a little to have LH2 broken and it hurts a lot more to have LH1 broken. What does this suggest about the organization of the two antenna complexes relative to the reaction center? Below are shown pictures of LH1, LH2, and the RC drawn as scientists think the protein products of the LH1, LH2, and RC genes might look. Pick the picture that best fits the data.
