  2. Glycolysis - Wikipedia

    en.wikipedia.org/wiki/Glycolysis

    The final step of glycolysis is catalysed by pyruvate kinase to form pyruvate and another ATP. It is regulated by a range of different transcriptional, covalent and non-covalent regulation mechanisms, which can vary widely in different tissues. [41] [42] [43] For example, in the liver, pyruvate kinase is regulated based on glucose availability.

    "The metabolic pathway of glycolysis converts glucose to pyruvate via a series of intermediate metabolites. Each chemical modification (red box) is performed by a different enzyme. Steps 1 and 3 consume ATP (blue) and steps 7 and 10 produce ATP (yellow). Since steps 6-10 occur twice per glucose molecule, this leads to a net production of energy."

    Glycolysis can be regulated at different steps of the process through feedback regulation. The step that is regulated the most is the third step. This regulation is to ensure that the body is not over-producing pyruvate molecules. The regulation also allows for the storage of glucose molecules into fatty acids. [5]

  6. Metabolic pathway - Wikipedia

    en.wikipedia.org/wiki/Metabolic_pathway

    Glycolysis results in the breakdown of glucose, but several reactions in the glycolysis pathway are reversible and participate in the re-synthesis of glucose (gluconeogenesis). [9] Glycolysis was the first metabolic pathway discovered: As glucose enters a cell, it is immediately phosphorylated by ATP to glucose 6-phosphate in the irreversible ...

  7. Glycogenolysis - Wikipedia

    en.wikipedia.org/wiki/Glycogenolysis

    In particular, glycogenolysis plays an important role in the fight-or-flight response and the regulation of glucose levels in the blood. In myocytes (muscle cells), glycogen degradation serves to provide an immediate source of glucose-6-phosphate for glycolysis, to provide energy for muscle contraction. Glucose-6-phosphate can not pass through ...

  8. Glucokinase - Wikipedia

    en.wikipedia.org/wiki/Glucokinase

    In the pancreatic beta-cell, glucokinase is a key regulator enzyme. Glucokinase is very important in the regulation of insulin secretion and has been known as the pancreatic beta-cell sensor. Mutations in the gene encoding glucokinase can cause both hyperglycemia and hypoglycemia because of its central role in the regulation of insulin release ...

  9. Phosphofructokinase 1 - Wikipedia

    en.wikipedia.org/wiki/Phosphofructokinase_1

    Glycolysis is the foundation for respiration, both anaerobic and aerobic. Because phosphofructokinase (PFK) catalyzes the ATP-dependent phosphorylation to convert fructose-6-phosphate into fructose 1,6-bisphosphate and ADP, it is one of the key regulatory steps of glycolysis. [ 1 ]
