When growing under defined conditions, cells of the yeast Saccharomyces cerevisiae absorbed ammonium more rapidly with glucose as carbon source than with maltose. Ammonium pool sizes and permease activity were also higher in the glucose-grown cells and the relationship implies that firstly, the sugar is a primary determinant of ammonium permease activity and, secondly, the activity of the permease largely determines both the rate of ammonium uptake and ammonium pool size in the first part of the fermentation.
