Glycolysis activity
WebGlycogen/glucose metabolism ( Fig. 151.1) Anaerobic glycolysis is the main metabolic pathway used in the setting of limited oxygen supply during exercise. It is used during high-intensity, sustained, isometric muscle activity.1 It is inefficient from an energetic standpoint and produces only two ATP molecules per glucose molecule, which is 19 ... WebThe regulation of glycolysis is determined by the activity of the enzymes hexokinase (or glucokinase in the liver and β-cells of the pancreas), phosphofructokinase-1, and pyruvate kinase. Common characteristics of these regulatory enzymes: They catalyze irreversible reactions in the glycolysis pathway.

Web13 hours ago · Hsu and partners found that DUSP6 deficiency regulates TCR signaling. In CD4 + T cells stimulated by TCR and lacking DUSP6 (DUSP6 –/–), the activity of the glycolysis rate-limiting HK was reduced and PFK activity was lost. Among these enzymes, PFK is the most important because its activity renders glycolysis irreversible.
