Method Assuming a volume for the cytosol of 10 to 12 µL (Douce, personal communication), the concentrations of fructose6P and UDPglucose in the cytosol after 4 to 8 min dark would be about 1.5 and 1.0 mM, which is in the range of the Km values reported for sucrose P synthase (Amir et al., 1982 PMID 16662338)
