21. In photosynthesis, water splitting donates electrons to the electron transport chain in photosystem II. 22. The electron transport chain is not affected and continues using oxygen, without producing ATP. 23. For the microbial perspective please reference the electron transport chain. 24. ROS can be formed from incomplete transfer of electrons through the electron transport chain. 25. Like MPP +, rotenone also interferes with complex I of the electron transport chain. 26. Ubiquinone is a key electron carrier in the electron transport chain of cellular respiration. 27. For details see Electron transport chain, and Microbial metabolism. 28. Their photosynthetic electron transport shares the same compartment as the components of respiratory electron transport. 29. Individual bacteria use multiple electron transport chains, often simultaneously. 30. The complete electron transport chain for " Chloroflexus " spp . is not yet known.
