Phosphofructokinase catalyzes the phosphorylation of fructose B-phosphate to fru

Question

Phosphofructokinase catalyzes the phosphorylation of fructose B-phosphate to fructose I ,6-bisphosphate in glycolysis. Fructose-1 ,6-bisphosphatase catalyzes the hydrolysis of fructose 1 ,6-bisphosphate to fructose 6-phosphate in gluconeogenesis. fructose 6- phosphate phosphofructokinase fructose 1 ,6-bisphosphatase fructose 1,6 - bisphosphate How does fructose-2,6-bisphosphate (F26BP) affect the activity of the enzymes phosphofructokinase-1 (PFK) and fructose I ,6-bisphosphatase (FBPase)? increases PFK activity, increases FBPase activity decreases PFK activity, increases FBPase activity decreases PFK activity, decreases FBPase activity increases PFK activity, decreases FBPase activity

Explanation / Answer

Option 4 is correct.

fructose-2,6-biphosphate increase the activity of PFK and decrease the activity of FBPase.
