In C4 plants, the initial fixation of CO2 occurs in mesophyll cells, forming a 4-carbon compound. This compound then travels to bundle sheath cells, where it releases CO2. What is the PRIMARY advantage of this spatial separation of CO2 fixation and the Calvin cycle?
Increases the efficiency of light absorption
Minimizes photorespiration by increasing CO2 concentration around RuBisCO
Reduces the need for water
Allows the plant to fix CO2 at night

PGAL
RuBP
PGA
OAA
