Figure 1: A schematic diagram of the electron-proton transport chain of oxygenic photosynthesis. Both PSI and PSII are multisubunit pigment protein complexes embedded in the thylakoid membrane of ...
Scientists found that cyanobacteria contained tiny sacks, called thylakoids. Inside these little sacks, photosynthesis can happen. Scientist estimate these fossils are around 1.75 billion years old.
The chloroplast thylakoid membrane is the site for the initial steps of photosynthesis that convert solar energy into chemical energy, ultimately powering almost all life on earth. The heterogeneous ...
