c4 photosynthesis

Definition Source References

C4 photosynthesis is an evolved metabolic mechanism for plant carbon fixation, in which atmospheric CO2 is first incorporated into a 4-carbon intermediate molecule. It allows for a more efficient process compared to C3 photosynthesis, especially in non-optimal water availability conditions and in the presence of high solar radiation.
