Rationale for change
This card incorrectly uses the term "positive feedback", as it implies that fructose-1,6-bisphosphate activating pyruvate kinase increases fructose-1,6-bisphosphate production. This does not occur. Rather, F1,6BP accumulates when glycolysis is active, and an increase in F1,6BP activates pyruvate kinase, a mechanism called feed-forward activation that promotes glycolysis. This term, feedforward or allosteric activation should be substituted for "positive feedback."
