Explain What Kind of Reaction Bacteriorhodopsin Performs and What It

Question

Examlex · Accepted Answer

The Answer is Bacteriorhodopsin absorbs light and goes through a photocycle involving excitation and relaxation and ultimately resulting in the pumping of one H⁺. This generates a proton motive force that can be used for ATP synthesis. Bacteriorhodopsin was thought to be limited to extreme halophilic archaea. In 2005, several researchers collected samples of seawater from the Mediterranean and Red seas. A community genome analysis was performed, including analysis of unculturable bacteria. The genomes from 13% of the marine bacteria were found to contain bacteriorhodopsin homologs, which were termed proteorhodopsins. Thus, a sizable proportion of marine phototrophy can be attributed to proteorhodopsin-producing organisms.
