Sir,
In CAM cycle during day, on breakdown of organic acids the carbon dioxide and phosphoenolpyruvate forms.My question is, why phosphoenolpyruvate donot react again with the released carbon dioxide?

Sir in CAM plants, if the stomata is closed during the day then how does photosynthesis take place as in photosynthesis co2 has to be taken from the atmosphere and o2 has to released in the atmosphere? Also how does respiation take place? Can we explain these phenomenon by saying that stomata donot get 100% closed and thus allow gaseous change to take place even in the so called closed condition?
