The enzyme of glycolytic pathway that forms fructose 1,6-bisphosphate is called phosphofructokinase-1 (PFK-1), which statements can’t distinguish it from a second enzyme (PFK-2) Phosphofructokinase-2.

#Unit 6. System Physiology – Plant
  1. PFK-2 that catalyzes the formation of fructose 2,6-bisphosphate from fructose 6-phosphate rather than fructose 1,6-bisphosphate in a separate pathway
  2. PFK-2 activity is regulated by phosphorylation while the PFK-1 activity is regulated by high conc of ATP and NADH etc
  3. more important regulator of plant glycolysis is the cytosolic concentration of PEP, which is an Activator of the plant ATP-dependent PFK-1 and inhibitor of PFK-2
  4. fructose 2,6-bisphosphate activates PFK-1 by increasing its apparent affinity for fructose 6-phosphate
