from a series of studies on the kinetics of uptake of glucose and fructose , including competition studies , the effects of inhibitors , radioactive assay of accumulated sugars and the distribution of label in accumulated sucrose it appeared that rate limitation for glucose or fructose uptake resides in the sequence of reactions leading to sucrose synthesis , rather than in a process mediated by a carrier protein .
