C3 plants have a straightforward photosynthesis pathway, but they suffer from photorespiration in hot weather, which wastes energy. C4 plants have an extra "pump" (the Hatch-Slack pathway using PEP carboxylase) to concentrate CO2 for the RuBisCO enzyme, effectively avoiding that loss. It’s like our old para club versus a modern air-conditioned bank—both get the job done, but one is more efficient in the heat. I remember struggling with this diagram during last borsha’s power cuts, the lantern light flickering over my notes, thinking how these plants adapted, just like we adapt in our own ways.
