The C fixed during photosynthesis is converted into sugar or sugar derivatives in photosynthetic source cells then is distributed to distal sink cells.

WebThe drawback to C4 photosynthesis is the extra energy in the form of ATP that is used to pump the 4-carbon acids to the bundle sheath cell and the pumping of the 3-carbon compound back to the mesophyll cell for conversion to PEP. This loss to the system is why C3 plants will outperform C4 plants if there is a lot of water and sun.
