Answer:
The cytochrome b6f is a large multi-subunit protein, which accepts electrons from the plastohydroquinone.
One electron moves linearly toward plastocyanin while the other goes through a cyclic process, which effectively pumps more protons into the thylakoid lumen.
Explanation:
The cytochrome b6f is distributed among both grana and stroma thylakoids equally. They are usually large and embedded in the membrane.
Mitochondria and chloroplast have similar DNA, which is not evidence for the endosymbiotic origins of mitochondria and chloroplasts.
According to the endosymbiotic theory, a chloroplast and a mitochondria were the independent prokaryotes. Both can be ingested by a large prokaryote and resist digestion. As a result, they continued as endosymbionts and eventually lost some of their autonomic properties. They divide by binary fission, have their own genetic material, possess 70s ribosomes, and Both include their own transcriptional and translational machinery.
Therefore, considering endosymbiotic origin theory, Both Mitochondria and chloroplast have similar DNA is not a piece of evidence.
