  2. Thylakoid - Wikipedia

    en.wikipedia.org/wiki/Thylakoid

    The thylakoid membrane is the site of the light-dependent ... The cytochrome b6f complex is part of the thylakoid electron transport chain and couples electron ...

  3. Photosystem - Wikipedia

    en.wikipedia.org/wiki/Photosystem

    Electrons travel through the cytochrome b6f complex to photosystem I via an electron transport chain within the thylakoid membrane. Energy from PSI drives this process [ citation needed ] and is harnessed (the whole process is termed chemiosmosis ) to pump protons across the membrane, into the thylakoid lumen space from the chloroplast stroma.

  4. Photosystem I - Wikipedia

    en.wikipedia.org/wiki/Photosystem_I

    Photosystem I [1] is an integral membrane protein complex that uses light energy to catalyze the transfer of electrons across the thylakoid membrane from plastocyanin to ferredoxin. Ultimately, the electrons that are transferred by Photosystem I are used to produce the moderate-energy hydrogen carrier NADPH. [2]

  5. Electron transport chain - Wikipedia

    en.wikipedia.org/wiki/Electron_transport_chain

    An electron transport chain (ETC [1]) is a series of protein complexes and other molecules which transfer electrons from electron donors to electron acceptors via redox reactions (both reduction and oxidation occurring simultaneously) and couples this electron transfer with the transfer of protons (H + ions) across a membrane.

  6. Light-dependent reactions - Wikipedia

    en.wikipedia.org/wiki/Light-dependent_reactions

    Light-dependent reactions of photosynthesis at the thylakoid membrane. Light-dependent reactions are certain photochemical reactions involved in photosynthesis, the main process by which plants acquire energy. There are two light dependent reactions: the first occurs at photosystem II (PSII) and the second occurs at photosystem I (PSI).

  7. Photosystem II - Wikipedia

    en.wikipedia.org/wiki/Photosystem_II

    It is located in the thylakoid membrane of plants, algae, and cyanobacteria. Within the photosystem, ... Water-splitting process: Electron transport and regulation.

  8. Chlororespiration - Wikipedia

    en.wikipedia.org/wiki/Chlororespiration

    This membrane contains an enzyme called NAD(P)H dehydrogenase which transfers electrons in a linear chain to oxygen molecules. [1] This electron transport chain (ETC) within the chloroplast also interacts with those in the mitochondria where respiration takes place. [2] Photosynthesis is also a process that Chlororespiration interacts with. [2]

  9. Chemiosmosis - Wikipedia

    en.wikipedia.org/wiki/Chemiosmosis

    For instance, in chloroplasts during photosynthesis, an electron transport chain pumps H + ions (protons) in the stroma (fluid) through the thylakoid membrane to the thylakoid spaces. The stored energy is used to photophosphorylate ADP, making ATP, as protons move through ATP synthase.
