Photosynthesis converts light energy into chemical forms while incorporating inorganic carbon into organic molecules. The overall water-carbon dioxide-sugar-oxygen bookkeeping conceals multiple stages and intermediate carriers. Respiration and other metabolism continue alongside it. This conceptual model tracks essential inputs without simulating enzyme kinetics, light saturation, temperature stress, stomatal regulation or species-specific photosynthetic pathways.
