‘04 The Uptake of Glucose in Yeast Cells Glucose is absorbed across the cell surface membrane (plasma membrane) of most cells. A convenient way to investigate this is to use a solution of glucose and a suspension of yeast cells. The amount of glucose taken up from the glucose solution by yeast cells in a fixed length of time can be measured. At the end of the fixed length of time‚ further uptake of glucose is prevented by transferring the yeast suspension to a boiling water bath to kill the yeast

enzymic reactions‚ and regulation of the underlying pathways have been studied in great detail in yeast. Anabolic pathways include reductive processes leading to the production of new cellular material‚ while catabolic pathways are oxidative processes which remove electrons from substrates or intermediates that are used to generate energy. Preferably‚ these processes use NADP or NAD‚ respectively‚ as co-factors. Although all yeasts are microorganisms that derive their chemical energy‚ in the from of

Introduction: Glucose is one of the few chemical constituents of the blood that can change noticeably in its concentration. Many diseases cause a change in glucose metabolism but the most frequent cause of an increase in blood glucose is diabetes mellitus. The early detection of diabetes is important to avoid the many complications of the disease. The glucose tolerance test commonly done by recommended level for adults of a 75 g glucose drink to be consumed within a 5 min time period. The timing
