FIG. 1.
Time series of HPLC chromatograms of extracts obtained after addition of l-[3H]glucose and d-[14C]glucose to d-glucose-consuming yeast cells exhibiting high-affinity d-glucose transport. The extracellular glucose concentration at the time of label addition was 13.3 mM. The cells were quenched in −40°C methanol at the indicated times after addition of label. The extracts and chromatograms were obtained as described in Material and Methods.
