Photosynthesis

概述

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.
