Answer 1

Glucose enters glycolysis directly at step 1

In muscles and kidneys, fructose enters glycolysis after being converted to fructose 6 phosphate at step3.

In liver, fructose enters glycolysis after being converted to glyceraldehyde 3 phosphate at step 5

In muscle, fructose may be phosphorylated by hexokinase to form fructose-6-phosphate and directly enter the glycolytic pathway.

The liver has fructokinase, which synthesizes fructose-1-phosphate. Aldolase and triose kinase generate glyceraldehyde-3-phosphate and dihydroxyacetone phosphate.

Glucose enters glycolysis directly at step 1

Galactose enters glycolysis after being converted to glucose 6 phosphate at step 2.

Galactose is converted to galactose 1 phosphate by galactokinase which is converted to glucose 1 phosphate and then it is converted to glucose 6 phosphate by the (enzyme phosphoglucomutase )which enters into glycolysis.
