Question
Which of the following is not produced in the pentose phosphate pathway?Group of answer choicesA) CO2B) Ribulose-5-phosphateC) NADHD) 6-phosphoglucono-δ-lactoneE) Erythrose-4-phosphate
Solution
The pentose phosphate pathway is a metabolic pathway parallel to glycolysis which generates NADPH and pentoses (5-carbon sugars) as well as Ribose 5-phosphate, a precursor for the synthesis of nucleotides.
Here are the products of the pentose phosphate pathway:
A) CO2 - Yes, it is produced in the oxidative phase of the pentose phosphate pathway.
B) Ribulose-5-phosphate - Yes, it is produced in the non-oxidative phase of the pentose phosphate pathway.
C) NADH - No, NADH is not produced in the pentose phosphate pathway. Instead, NADPH is produced.
D) 6-phosphoglucono-δ-lactone - Yes, it is produced in the oxidative phase of the pentose phosphate pathway.
E) Erythrose-4-phosphate - Yes, it is produced in the non-oxidative phase of the pentose phosphate pathway.
So, the correct answer is C) NADH. It is not produced in the pentose phosphate pathway.
