6-phosphogluconolactone is hydrolysed by which enzyme to produce 6 molecules of 6-phosphogluconic acid.
Lactonase
6-phosphogluconic acid dehydrogenase
Ribulose phosphate-3-epimerase
Pentose phosphate isomerase
The enzyme lactonase hydrolyzes 6-phosphogluconolactone and produces 6 molecules of 6-phosphogluconic acid.
The enzyme 6-phosphogluconic acid dehydrogenase decarboxylates phosphogluconic acid by oxidation.
In the presence of the enzymes ribulose phosphate-3-epimerase and pentose phosphate isomerase, 6 molecules of ribulose-5-phosphate isomerize into 4 molecules of xylulose-5-phosphate and 2 molecules of ribose-5-phosphate produce respectively.
Hence, option 1 is the correct answer.
