Definition of Plastoquinone. Meaning of Plastoquinone. Synonyms of Plastoquinone

- Plastoquinone (PQ) is a terpenoid-quinone (meroterpenoid) molecule involved in the electron transport chain in the light-dependent reactions of photosynthesis...
- Photosystem II (or water-plastoquinone oxidoreductase) is the first protein complex in the energy-dependent reactions of oxygenic photosynthesis. It is...
- series of experiments to demonstrate that it is pheophytin and not plastoquinone that serves as the primary electron acceptor in photosystem II. Using...
- plastocyanin + 2 H+ [side 1] ⇌ {\displaystyle \rightleftharpoons } plastoquinone + 2 reduced plastocyanin + 4 H+ [side 2]. The reaction is analogous...
- shuttle electrons between them. These carriers are plastoquinone and plastocyanin. Plastoquinone shuttles electrons from photosystem II to the cytochrome...
- electrons from water to a mobile electron carrier in the membrane called plastoquinone: H 2O → P680 → P680* → plastoquinol Plastoquinol, in turn, transfers...
- the denomination of a cationic derivative of the plant antioxidant plastoquinone. In 1969, triphenylphosphonium (TPP, charged triphenylphosphine) was...
- are transferred to protein-bound plastoquinone (PQA) and then to unbound plastoquinone (PQB). This reduces plastoquinone (PQ) to plastoquinol (PQH2) which...
- naturally occurring 1,4-benzoquinone involved in respiration apparatus. Plastoquinone is a redox relay involved in photosynthesis. Pyrroloquinoline quinone...
- It blocks the QB plastoquinone binding site of photosystem II, disallowing the electron flow from photosystem II to plastoquinone. This interrupts the...
