One of the key enzymes in the pentose phosphate pathway is glucose-6-phosphate dehydrogenase (G6PDH). This enzyme is responsible for oxidizing glucose-6-phosphate into the next intermediate in the pathway, with co-occuring production of NADPH. Which of the following is most likely to be true about the regulation of this enzyme?
