Photochemical phase or Light reaction
The light reaction is the first stage of photosynthesis that occurs in the thylakoid membrane of the chloroplast. It requires light energy to break down water molecules into oxygen and hydrogen ions. The hydrogen ions are used to generate ATP and NADPH, which are used in the second stage of photosynthesis, the dark reaction.
Process of Light Reaction:
1. Absorption of Light Energy: Chlorophyll pigments present in the thylakoid membrane absorb light energy and transfer it to the reaction center.
2. Generation of ATP: The absorbed light energy is used to generate ATP by the process of photophosphorylation.
3. Generation of NADPH: The absorbed light energy is also used to generate NADPH by the process of photoreduction.
4. Splitting of Water Molecules: Water molecules are split into oxygen and hydrogen ions by the process of photolysis.
5. Release of Oxygen: The oxygen produced by the photolysis of water is released into the atmosphere.
Importance of Light Reaction:
1. Production of ATP and NADPH: The light reaction produces ATP and NADPH, which are used in the dark reaction to synthesize glucose.
2. Release of Oxygen: The oxygen produced by the light reaction is released into the atmosphere, which is essential for the survival of living organisms.
3. Maintenance of Chloroplast: The light reaction helps in the maintenance of chloroplast by generating ATP, which is used to power various metabolic processes in the chloroplast.
Conclusion:
The light reaction is a critical process in photosynthesis that generates ATP and NADPH, which are used in the dark reaction to synthesize glucose. It also releases oxygen into the atmosphere, which is essential for life on earth.
