PSIIplastoquinone
PSII plastoquinone refers to the plastoquinone molecule that functions within Photosystem II (PSII) of the photosynthetic apparatus in plants and other photosynthetic organisms. Plastoquinones are small, lipid-soluble molecules that act as mobile electron carriers. In PSII, plastoquinone plays a crucial role in the electron transport chain.
Specifically, the primary plastoquinone molecule in PSII is often denoted as Q A, which is tightly bound
The interaction with Q B is particularly important because it allows for the sequential reduction of Q
