“SHORT CIRCUITS in the broken Q-cycle. Despite its sluggishness, the very existence of this short-circuit is important because it represents an “emergency exit” pathway which bypasses the Q-cycle. This reaction thus allows the quinol-plastocyanin oxidoreductase activity to occur and thus the entire photosynthetic chain to function, even with a non-functional Q cycle.”
