Comments There is a much greater density per unit membrane area of photochemical reaction centres in an ion-pumping rhodopsin ‘purple membrane’ (~270 nmol/m^2, 135 nmol/m^2 if half of the membrane is purple membrane, allowing room for F0F1-type ATP synthetases, respiratory enzymes and solute transporters), than in the thylakoid membrane of an oxygenic phototroph (~5 nmol/m^2 for each photosystem for a sun-adapted or acclimated vascular plant).
