Photosynthesis in C4 plants is relatively less limited by atmospheric levels because:
| 1. | The primary fixation of CO2 is mediated via PEP carboxylase |
| 2. | Effective pumping of CO2 into bundle sheath cells |
| 3. | Four carbon acids are the primary initial CO2 fixation products |
| 4. | RuBisCO in C4 plants has a higher affinity for CO2 |
