Plastoquinone-9

... also be like the ferrodoxin and the plastocyanin, in which the enzymes are membrane-bound to only one one side of the whole membrane, or even like plastoquinone in which it is inside the membrane). And last is "receptor". The enzyme can have its "active" site on the outside ...

... the effect of adding strong electron acceptors. What impact would this have on the pH shift if the electron acceptor was able to out compete plastoquinone for electrons? My initial guess after reading chapter 10 of the eighth edition Campbell & Reece Biology text book, is that the pH ...

the false statement is C. Chlorophyll molecules do not donate protons to anything. P680 donates two electrons to the next acceptor in the chain, plastoquinone. Those electrons travel down through the cytochrome chain to plastocianin to eventually rich P700. P700 can donate electrons to NADP+, ...

... ACS). http://www.princeton.edu/~biosolar/ All oxygenic phototrophs extract electrons and protons from water and use them to reduce NADP+ and plastoquinone for use as energy sources for metabolism such as Calvin cycle CO2 fixation and other pathways. However, some microbial oxygenic phototrophs ...
