WebThe most important of these compounds is glucose, which can be used by the plant for energy or stored for later use. B. Light reactions Photosynthesis Light reactions, also known as the light-dependent reactions, are the first stage of photosynthesis, occurring in the thylakoid membranes of chloroplasts. WebApr 8, 2024 · Fig: Process of photosynthesis Plant leaves absorb the photons from sunlight that excite chlorophyll and activate electrons. In the first step, the water absorbed by plant roots is split into oxygen and hydrogen ions. Then the excited electrons from ATP and NADPH. This process happens through the electron chain. WebHere are the basic steps: Light absorption in PSII. When light is absorbed by one of the many pigments in photosystem II, energy is passed inward... ATP synthesis. The high-energy electron travels down an electron transport chain, losing energy as it goes.
