==== Respiration ====
[[Cellular respiration|Respiration]] in cyanobacteria can occur in the thylakoid membrane alongside photosynthesis,<ref name="Vermaas_2001">{{cite book |title=Photosynthesis and Respiration in Cyanobacteria. eLS. | vauthors = Vermaas WF |date=2001 |publisher=[[John Wiley & Sons]], Ltd |isbn=978-0-470-01590-2 |doi=10.1038/npg.els.0001670 |chapter=Photosynthesis and Respiration in Cyanobacteria}}</ref> with their photosynthetic [[Electron transport chain|electron transport]] sharing the same compartment as the components of respiratory electron transport. While the goal of photosynthesis is to store energy by building carbohydrates from CO<sub>2</sub>, respiration is the reverse of this, with carbohydrates turned back into CO<sub>2</sub> accompanying energy release.

Cyanobacteria appear to separate these two processes with their plasma membrane containing only components of the respiratory chain, while the thylakoid membrane hosts an interlinked respiratory and photosynthetic electron transport chain.<ref name="Vermaas_2001" /> Cyanobacteria use electrons from [[succinate dehydrogenase]] rather than from [[Nicotinamide adenine dinucleotide phosphate|NADPH]] for respiration.<ref name="Vermaas_2001" />

Cyanobacteria only respire during the night (or in the dark) because the facilities used for electron transport are used in reverse for photosynthesis while in the light.<ref name="Armstrong_2014">{{cite book |url=https://www.press.uchicago.edu/ucp/books/book/chicago/H/bo16465693.html |title=How the Earth Turned Green: A Brief 3.8-Billion-Year History of Plants | vauthors = Armstronf JE |date=2015 |publisher=The [[University of Chicago Press]] |isbn=978-0-226-06977-7}}</ref>
