Which outcome occurs in CAM plants when environmental drought induces prolonged stomatal closure?

💡 Explanation

When drought leads to stomatal closure, CAM plants experience restricted CO2 uptake during the day; photorespiration results increasing the concentration of phosphoglycolate because RuBisCO inappropriately binds O2 instead of CO2. Therefore buildup of toxic photorespiration intermediates occurs, instead of other adaptations which require different enzymatic activities.
