Anoyher place in ncert its given that all monosaacharides substrate are first converted to glucose before entering glycolysis, but here its written fructose directly enters..so what is true?

Dear Student, Fructose can be converted to Glucose-6-phosphate directly. Actually hexokinase can readily act on Fructose also, so it can be directly converted to glucose-6-phosphate. Both the statements of NCERT are correct, since the statement you read earlier was a general implication where fructose is a special case. Interestingly you would note that Fructose has the highest affinity for the enzyme hexokinase, even more than glucose. Regards
