| Adaptation | C4 Plant (e.g., corn, sugarcane) | CAM Plant (e.g., cacti, pineapple) | | :--- | :--- | :--- | | | Yes (mesophyll cells fix CO2 into malate; bundle sheath cells run Calvin cycle) | No | | Temporal separation of carbon fixation | No | Yes (open stomata at night to fix CO2 into malate; Calvin cycle runs during the day) | | Minimizes photorespiration | Yes | Yes | | Initial CO2 acceptor | PEP carboxylase (in mesophyll) | PEP carboxylase (at night) |

Mastering Biology Chapter 10 typically covers Photosynthesis (in Campbell Biology textbooks) or Meiosis and Sexual Life Cycles

"The final electron acceptor of the light reactions is NADP+ , which becomes reduced to NADPH ."
