In 1970 Mayr stated that "species are formed by groups of potentially intercrossing populations that are reproductively isolated from others". The biological concept of species puts emphasis on existence of barriers that limit the gene flow among groups within the same species
The thylakoid membrane is a site of light-determined photosynthetic responses and is arranged into multi-lamellar and exceptionally stacked structures in cyanobacteria and chloroplasts. The fluid compartment encased by the thylakoid film is known as the thylakoid lumen.
The primary capacity of the lumen is thought to go about as a sink for protons and inorganic particles translocated during the light-driven photosynthetic electron move.
Then again, developing proof demonstrates that the thylakoid lumen is metabolically dynamic.
Hence, the answer is option c "jump to molecules in the membrane of the thylakoids".
