Mechanism of CO 2 Fixation in C 4 Plants CO 2 fixation occurs when CO 2 is bonded to a 3-carbon compound to produce a 4-carbon compound. This enzyme functions well even at extremely low CO 2 concentrations because it is unaffected by oxygen. This CO 2 fixation occurs within the mesophyll cells that surround the bundle sheath cells. The 4-carbon compound then moves into the bundle sheath and releases the
