Question

30.
Fructose is metabolized by
(1) fructose 1-phosphate pathway
(2) fructose 6-phosphate pathway
(3) glyceraldehyde 3-phosphate pathway
(4) Both (1) and (2)​

Answer 1

Answer:

1-phosphate is then split into glyceraldehyde and dihydroxyacetone phosphate, an intermediate in glycolysis. This aldol cleavage is catalyzed by a specific fructose 1-phosphate aldolase. Glyceraldehyde is then phosphorylated to glyceralde-hyde 3-phosphate, a glycolytic intermediate, by triose kinase.

Answer 2

Explanation:

option (3) is correct...
