"If [investigators] assume only passive sodium transport, sodium should indeed accumulate intracellularly, owing to the membrane potential, which is negative inside. [They] calculated the plasma membrane potential that would be required to achieve the observed 140-
fold accumulation, and obtained )128 mV. This seems a realistic value, as membrane potentials between -50
and -300 mV have been found for fungi [primary sources]." |
