The effects of CF on metabolism. Glycogen phosphorylase and glycogen synthase catalyze part of the reactions that are shown in the drawing, and are therefore noted as enzyme et al. The levels of glucose, glucose- 6-phosphate, fructose-6-phosphate and fructose-1,6-bisphosphate were measured by Jang et al.22 and Jang and Gomer.28 The arrows indicate the effects of CF on the levels of each intermediates or metabolites (up arrow for increasing the levels, and down arrow for decreasing the levels).
