Photosynthesis: Anabolic Process Converting Inorganic to Organic
Photosynthesis converts inorganic matter into organic using solar light. Sunlight's energy is converted into chemical energy within organic compounds. During photosynthesis, oxygen (O2) is released into the atmosphere. The overall process can be summarized as: CO2 + H2O + Light -> Organic Matter + O2.
However, this simplified equation doesn't reflect the actual process. The oxygen released comes from water, not carbon dioxide. Glucose formation and oxygen release are independent processes.
Light Phase (Hill Reaction)
The light phase occurs in the thylakoids, where photosystems are located. It requires light and produces:
- Reducing power: NADPH + H+
- Energy: ATP (produced using sunlight)
