Stroma , lies inside the envelope but outside the thylakoid emmbranes. Thylakoid lumen . Inside the thylakoids. Glyceraldehyde 3-phosphate Electron transport in chloroplasts Sunlight is absorbed through a pigment called chlorophyll . Electron transport in chloroplasts is accomplished by the use of two photosystems.
Light is absorbed and trasnferred to reaction center chlorophylls.
High-energy electrons are then transferred through a series of carriers to plastoquinone . 3.Plastoquinone carries electrons from PS II to the cytochrome bf complex , electrons are then transferred to plastocyanin and additional protons are pumped into the thylakoid lumen. The high-energy electrons derived from this process are transferred through a series of carriers and is coupled to a proton gradient, which drives the chemiosmotic synthesis of ATP via ATP synthase . From PSII, electrons are carried by plastocyanin to PS I. 5. I also absorbes photons to generate high-energy electrons.
