D-xylulose 5-phosphate + D-ribose 5-phosphate two optical methods for transketolase activity assay using only one substrate, xylulose 5-phosphate or glycol aldehyde. For transketolase activity assay in the first method, it is necessary to add auxiliary enzyme, glyceraldehyde phosphate dehydrogenase. It is not needed in the second method. The range of transketolase concentration in the activity assay is 0.036-0.144 U/ml for the first method and 1.8-6.8 U/ml for the second one Saccharomyces cerevisiae sedoheptulose 7-phosphate + D-glyceraldehyde 3-phosphate
