The enzyme phosphofructokinase (PFK) is inhibited by ATP and activated by AMP and fructose-2,6- bisphosphate (F2,6BP, a molecule that regulates glycolysis and ...
WebPhosphofructokinase is the main enzyme controlled in glycolysis. High levels of ATP, citrate, or a lower, more acidic pH decrease the enzyme’s activity. An increase in citrate concentration can occur because of a blockage in the citric acid cycle. included in m365WebThe most important enzyme for regulation of glycolysis is phosphofructokinase, which catalyzes formation of the unstable, two-phosphate sugar molecule, fructose-1,6-bisphosphate 4 ^4 ... when ATP levels are high it is inhibited and less fructose-1,6-bisphosphate will be created when ADP levels are high it will be activated and more … included in italianoWebPhosphofructokinase is an allosteric enzyme in the pathway that breaks down glucose to produce ATP. Regulation of glycolysis is directly related to the level of ATP and citrate. If ATP or citrate levels are high, phosphofructokinase is inhibited.
