Chapter 24: Photosynthesis: Quantum Coherence and Carbon Fixation

Photosynthesis is the canonical production act of the source sector: CO₂ + H₂O + light → organic carbon + O₂. The light reactions in photosystems I and II split water and drive electron transport, while the Calvin cycle fixes carbon via RuBisCO. Quantum coherence in the FMO complex suggests that energy transfer exploits quantum effects, though the biological mechanism remains at conjectural scope.
