Photosynthesis

6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

نظرة عامة

The most important photochemical reaction on Earth. Plants, algae, and cyanobacteria use chlorophyll to capture sunlight and convert carbon dioxide and water into glucose and oxygen. The light reactions split water at photosystem II, while the Calvin cycle fixes CO₂. This reaction produces virtually all atmospheric oxygen and is the foundation of most food chains.

مثال من الحياة اليومية

Every bite of food you eat and every breath of oxygen you inhale ultimately traces back to photosynthesis.

الأهمية الصناعية

Photosynthesis fixes about 120 billion tonnes of carbon annually. Artificial photosynthesis research aims to produce clean fuels from sunlight.
