Quizplus · Accepted Answer

Bacteriorhodopsin is a protein found in the plasma membrane of the archaeon Halobacterium salinarum. It acts as a proton pump, which is driven by the energy it captures from light. This process involves the absorption of light by retinal (a derivative of vitamin A), which is bound to bacteriorhodopsin, leading to a conformational change that facilitates the movement of protons across the membrane, thereby generating a proton gradient used for ATP synthesis.
