Simulation of a high- and low-affinity sugar-uptake system in Chlorella by a pH-dependent change in the Km of the uptake system.

E Komor1, W Tanner.   

Abstract

Chlorella vulgaris cells take up hexoses by a proton cotransport system. Depending of the pH of the medium either a high- or a low-affinity uptake system or both these systems can be observed. In the latter case the cells exhibit distinct biphasic uptake kinetics.
