Answer: NaDP+/NaDPH and D. glucose 6‑phosphate dehydrogenase
Explanation:
Pentose Phosphate pathway could be generally divided into oxidative and non-oxidative. The rate-limiting irreversible step in the oxidative step defined by the glucose-6-phosphate dehydrogenase which requires the reduction of NADP to NADPH. The enzyme is highly selective for the NADH and its activity is tightly dependent on the presence of the NADP
