Pentose Phosphate Pathway
Q3.3-Glucose-6-phosphate (G6P) is a central metabolite in carbohydrate
metabolism. Describe the regulatory mechanism that controls the relative
flux of G6P through the Pentose Phosphate Pathway or the Glycolytic
Pathway.

Expert Solution

Step 1

Introduction :

Pentose phosphate pathway :

Glycolysis produces the first 6-carbon molecule necessary for the pentose phosphate pathway by breaking down the simple sugar, glucose. A phosphate group is added to glucose during the first stage of glycolysis, transforming it into glucose-6-phosphate, another 6-carbon molecule. Any molecules of glucose-6-phosphate that are available, whether they are created by glycolysis or other processes, can be used by the pentose phosphate pathway.
