WebMay 1, 1994 · The photosynthetic gas-exchange rates and various biochemical components of photosynthesis, including ribulose-1,5-bisphosphate carboxylase (Rubisco) content, cytochrome (Cyt) f content, and the activities of two sucrose synthesis enzymes, were examined in young, fully expanded leaves of rice (Oryza sativa L.) grown hydroponically … WebCytochrome Complex in Electron Transport. A cytochrome complex plays a key part in electron transport associated with the membranes of the thylakoids in the process of photosynthesis. It accepts electrons from Photosystem II through plastoquinone and contributes to proton transport across the membrane.
In photosynthesis, the cytochrome b6f complex functions to mediate the transfer of electrons and of energy between the two photosynthetic reaction center complexes, Photosystem II and Photosystem I, while transferring protons from the chloroplast stroma across the thylakoid membrane into the lumen. Electron transport via cytochrome b6f is responsible for creating the proton gradient that … WebThe cytochrome b6f complex is an integral membrane protein complex which catalyzes electron transfer from plastoquinol to plastocyanin and pumps protons across the thylakoid membrane. Its turnover rate in chloroplasts can be up to 300 s −1 (reviewed in Hauska et al., 1983; Hope, 1993; Cramer et al., 1994 ).
