When stomates are closed during the day, the C4 acids are transferred from vacuoles to the chloroplasts where the Calvin cycle occurs to produce glucose."@en, "Vía bioquímica en la que la fijación de carbono inicial ocurre en las células mesófilas externas durante la noche cuando los estomas se abren. Cuando los estomas se cierran durante el día, los ácidos C4 se transfieren desde las vacuolas a los cloroplastos, donde se verifica el ciclo de Calvin y se produce glucosa."@es ;
