Glucose uptake in the yeast Saccharomyces cerevisiae.

The glucose uptake of Saccharomyces cerevisiae cells in sporulation medium for 3 h was higher than that of cells in 5.5 mM glucose medium. This difference might be due to the change in cell structure which is necessary for the sporulation process. In both types of cells, the glucose uptake activity became higher as the glucose concentration of the medium decreased.
