Light-dependent reactions of photosynthesis
Jackie Shukin・2 minutes read
The light-dependent reactions of photosynthesis take place in the chloroplasts, involving crucial proteins like PS2, PS1, and ATP synthase to produce ATP and NADPH through a series of steps including photo excitation, electron transport chain, photolysis, chemiosmosis, and reduction reactions. These reactions occur within the thylakoid and along the thylakoid membrane before releasing ATP and NADPH into the stroma for further use in photosynthesis.
Insights
- Light dependent reactions of photosynthesis take place in chloroplasts, specifically in the thylakoid and along its membrane, leading to the creation of ATP and NADPH, which are crucial for subsequent steps.
- PS2, PS1, and ATP synthase are key proteins in these reactions, with PS2 absorbing sunlight to energize chlorophyll, an electron transport chain moving electrons, photolysis splitting water, and chemiosmosis utilizing ATP synthase to generate ATP and NADPH.
