| Method |
Multiplying
the density of the photochemical reaction centres (BNID 105044,105045) by the
maximum specific reaction rate (BNID 105050,105051) gives a flux rate of energised
product on an area basis. For rhodopsin this is ~0.95 µmol
H+/(m^2×s^1), whereas for oxygenic photosynthesis it is
~1.5 µmol electron/(m^2×s^1) moved from water to NADP+ and
4.5 µmol H+/(m^2×s^1) (H+ : electron = 3: Falkowski and Raven
2007) (Table link). |
| Comments |
Bacteriorhodopsin is an integral membrane protein usually found in two-dimensional crystalline patches known as "purple membrane", which can occupy up to nearly 50% of the surface area of the archaeal cell. Data in table for purple membrane with half the area occupied by ion-pumping rhodopsin. See BNID 105054,105055 |
