Oxygenic - Study guides, Revision notes & Summaries

Oxygenic photosynthesis -found in cyanobacteria -uses H2O as proton donor -Produces O2 -2 photosystems -linear flow of electrons -uses Calvin cycle -uses Chl a Anoxygenic photosynthesis -uses H2S as proton donor -produces S -green sulphur bacteria use reverse cycle to incorporate CO2 rather than produce it -green non-sulphur bacteria use the hydroxypropionate pathway (ancestral pathway) Photosystem I -similar to Chlorobi (Green S. bacteria) and Firmicutes (Heliobacterium) -has ferrodoxin Phot...
