C4 plants minimize photo-respiration by using a more efficient enzyme to fix CO2

Question

C4 plants minimize photo-respiration by using a more efficient enzyme to fix CO2 this enzyme is called RubisCO. so they have greater productivity in high temperatures.

In the presence of oxygen, Rubisco can acts as an oxygenase catalyzing the fixation of oxygen rather than carbon deliver CO2 to rubisco thereby maximizing the carbohydrate formation and preventing product loss due to photorespiration.

C4 plants perform the calvin cycle in the bundle sheath cell. CAM open their stomata at night and store the CO2 until morning.

These plants CO2 fixed into vacuoles during the night and incorporate it into malic acid similar to the C4 pathway.During the DAY the malic acid transfer CO2 to rubisco and carbohydrate is made.

Explanation / Answer

B) How do C4 and CAM plants manage to more efficiently fix carbon under conditions of high temperature and intense sunlight?
