Linked from

The 10 pages that link to Photosystem I, each with the reason it gives.

• PhotosynthesisBroader topic: It helps generate the reducing power that drives carbon fixation.

• ChloroplastBroader topic: It re-energizes electrons downstream of Photosystem II in the chloroplast’s light reactions.

• ChlorophyllRelated: Its chlorophyll absorbs light that re-energizes electrons arriving from the photosynthetic electron transport chain.

• Photosystem IIRelated: It acts downstream of photosystem II in linear electron transport.

• Oxygenic photosynthesisBroader topic: It raises electrons from water to the energy level needed to reduce NADP⁺.

• Chlorophyll aRelated: Its reaction-center chlorophyll a absorbs light to drive a second major charge separation.

• Photosynthetically active radiationBroader topic: It absorbs PAR to re-energize electrons during photosynthesis.

• ThylakoidRelated: It captures a second input of light energy within the thylakoid electron-transport chain.

• Light-dependent reactionsBroader topic: It supplies the high-energy electrons used to make NADPH.

• ParaquatRelated: It supplies electrons that paraquat diverts from normal photosynthetic pathways.
