A. Oxidation of glucose 6-phosphate to 6-phosphoglucono-δ-lactone
B. Oxidation of 6-phosphogluconate to ketopentose ribulose 5-phosphate
C. Reduction of 6-phosphoglucono-δ-lactone to glucose 6-phosphate
D. Reduction of ketopentose ribulose 5-phosphate to 6-phosphogluconate
Answer:A
What is the first reaction of the pentose phosphate pathway?
A. Oxidation of glucose 6-phosphate to 6-phosphoglucono-δ-lactone B. Oxidation of 6-phosphogluconate to ketopentose ribulose 5-phosphate C. Reduction of 6-phosphoglucono-δ-lactone to glucose 6-phosphate D. Reduction of ketopentose ribulose 5-phosphate to 6-phosphogluconate
Explanation: The first reaction of the pentose phosphate pathway is the oxidation of glucose 6-phosphate to 6-phosphoglucono-δ-lactone by glucose 6-phosphate dehydrogenase.
