Sucrose maltose, and lactose are common dietary disaccharides, Their monosaccharide components are substrates for the pathway, but some must particlpate in additional reactlions before they can act as substrates for a glycolytic enzyme Asaresuit all do not enter glycolysis at the same step. in muscle cells, which enzyme would act as the rate-limiting step to regulate entry of products from all three dietary disaccharides into glycolysis?

A. phosphoglucose isomerase
B. hexokinase
C. aldolase
D. phosphoglucose -1
