Which outcome occurs in CAM plants during the night due to temporal separation of pathways?

💡 Explanation

During the night in CAM plants, CO2 fixation via PEP carboxylase occurs because stomata open at night to minimize water loss, allowing CO2 to be converted into a four-carbon acid. Therefore, CO2 fixation results, rather than photorespiration, Rubisco fixation due to daytime constraints or open stomata which exacerbate water loss.
