Webcyclic In the ________ electron pathway, the electrons are recycled back to photosystem I. This produces ATP but not NADPH. thylakoid ATP Production - The electron transport chain produces excess H+ ions that are pumped into the __________ space, creating an electrochemical gradient there. chemiosmosis This form of photophosphorylation occurs on the stroma lamella, or fret channels. In cyclic photophosphorylation, the high-energy electron released from P700, a pigment in a complex called photosystem I, flows in a cyclic pathway. The electron starts in photosystem I, passes from the primary election acceptor to ferredoxin and then to plastoquinone, next to cytochrome b6f (a similar complex to that found in mitochondria), and finally to plastocyanin before returning to phot… flat sea fish 5 lettersWebA) Both photosynthesis and cellular respiration occur in plant cells.
