The Z-scheme of photosynthesis is an electron rollercoaster — electrons from water ride up to PS II, crash to PS I, then get boosted again to make NADPH. Watch it run.
›Light reactions (thylakoid): water splitting, Z-scheme, ATP synthesis (photophosphorylation), NADPH.
›Calvin cycle (stroma): CO₂ fixation by RuBisCO → 3-PGA → G3P → RuBP regeneration.
