Cytochrome in photosynthesis
WebAbstract The cytochromes that function in photosynthesis in cyanobacteria, algae, and higher plants have, like the other photosynthetic catalysts, been largely conserved in … WebThe electrons from Complexes I and II are passed to the small mobile carrier Q. Q transports the electrons to Complex III, which then passes them to Cytochrome C. Cytochrome C passes the electrons to Complex IV, which then passes them to oxygen in the matrix, forming water. It takes two electrons, 1/2 O2, and 2 H+ to form one water …

WebJan 25, 2024 · The energy released during the transport of electrons from the cytochrome is used in the photophosphorylation of \ ( {\rm {ADP}}\) to produce \ ( {\rm {ATP}}\). Hydrogen is firmly bonded to oxygen in water molecules, and it can only be split with the use of energy. Light is the source of this energy. WebThe photosynthetic electron transport chain is embedded in the chloroplast's thylakoid membrane. It consists of four large protein complexes, one small protein complex, and three smaller mobile carrier proteins. The space within the thylakoid membrane is called the lumen. The space surrounding the membrane is called the stroma. MORE DETAIL 3.)
