On the extent of the electrical potential across the thylakoid membrane induced by continuous light in Chlorella cells.

ABSTRACT

The extent of the electrical potential delta phi(SS) across the thylakoid membrane of Chlorella cells was estimated under steady state conditions. This has been achieved by comparing the absorption change which occurs after continuous light is switched off with a calibrated field indicating absorption change induced by flash light. Under saturating light conditions delta phi(SS) is in the order of 100 mV.
