Question

The net equation for the oxidative reactions of the pentose phosphate pathway is glucose-6- phosphate + 2NADP^+ + H_2 O rightarrowribulose - 5- phosphate + 2NADPH+ CO_2 + 2H^+ Determine which of the following statements about the pentose phosphate pathway are true. Glucose-6-phosphate is common to glycolysis and the pentose phosphate pathway. The pentose phosphate pathway contributes to nucleotide synthesis. Glucose-6-phosphate is reduced to ribulose-5-phosphate in this series of reactions. Carbon atoms from the pentose sugar products may enter the glycolytic pathway.

Explanation / Answer

True: 1, 2 and 4

False: 3

Glucose 6 phosphate is oxidized to ribulose 5 phosphate in this series of reaction. (The statement says it is reduced)
