The reducing poweris in the form of electrons carried in NADH and FADH, which are producedin the TCA cycle and passed to a membrane-bound electron transport system(ETS) terminated by oxygen (aerobic respiration) or another electron acceptor(anaerobic respiration).

The above sketch of the cyclic process is patterned after a visualization in Moore, et al. Two photons from either the red or blue end of the spectrum fit the sensitive response of the . They are captured by the and transferred to the Photosystem I reaction center, which contributes two high energy electrons to the primary electron receptor. They are passed to ferrodoxin (Fd), an iron containing protein which acts as an electron carrier. A second electron carrier plastoquinone (Pq) carries the electrons to a complex of two cytochromes. In the process, energy is provided to produce a proton gradient across the membrane which can be used for the ADP to ATP conversion. The electrons are returned by plastocyanin (Pc) to the P700 pigment in the reaction center to complete the cycle.
