Quizplus · Accepted Answer

Photorespiration occurs in the presence of light and high oxygen levels, which are conditions present in Cell II. Cell I has adapted to minimize photorespiration with its unique carbon fixation pathway (C4 photosynthesis) and would not experience significant levels of photorespiration. Additionally, photorespiration does not occur at night as there is no light available for the photochemical reactions that drive the process.
