When CAM plants transition to shade, which outcome results due to insufficient light?

💡 Explanation

CAM plants initially fix CO₂ into malate; however, decreased light compromises the regeneration of RuBP through the Calvin cycle. Therefore, malate excessively accumulates in vacuoles at night, because the necessary enzymatic processes become limited, rather than switching primary carbon fixation to daytime only.
