| Abstract: | The yeastCandida beverwijkii was found to transport several monosaccharides against a concentration gradient. The process is mediated by a mobile carrier
and shows a pronounced pH dependence. It is tightly coupled with metabolism and only potassium sorbate uncoupled the equilibrating
from the active transport component. Kinetic analysis of uptake and efflux at high monosaccharide concentrations indicates
an active transport operating either into or out of cells.
