    Study Notes

    Glycolysis is a central metabolic pathway that plays a key role in the oxidation of glucose to pyruvate, which is a process that occurs in all living cells[1 Step 1: When a molecule of glucose enters the cell, it is immediately phosphorylated by the enzyme hexokinase to glucose-6-phosphate using the phosphate[1 Step 1: When a molecule of glucose enters the cell, it is immediately phosphorylated by the enzyme hexokinase to glucose-6-phosphate using the phosphate[1 Step 1: When a molecule of glucose enters the cell, it is immediately phosphorylated by the enzyme hexokinase to glucose-6-phosphate using the phosphate[1 Step 1: When a molecule of glucose enters the cell, it is immediately phosphorylated by the enzyme hexokinase to glucose-6-phosphate using the phosphate[1
