21. 1 ) What is the logic of glycolysis ?? 22. In glycolysis , glucose and glycerol are metabolized to pyruvate via the glycolytic pathway. 23. Thus, glycolysis is inhibited in the liver but unaffected in muscle when fasting. 24. Important for glycolysis to proceed, the hexokinase reaction activates glucose for subsequent steps. 25. TPI plays an important role in glycolysis and is essential for efficient energy production. 26. PER2 in turn enhances oxygen-efficient glycolysis and hence provides cardioprotection from ischemia. 27. Aberrant expression of LIN28 has been seen to regulate aerobic glycolysis to facilitate cancer proliferation 28. The intermediates provide entry points to glycolysis . 29. Cells performing aerobic respiration synthesize much more ATP, but not as part of glycolysis . 30. The resulting trioses are identical to those obtained in glycolysis and can enter the pyruvate.
