<prompt> Decreased glycolytic activity impairs oxygen transport by hemoglobin due toReduced energy productionDecreased production of 2,3 - bisphosphoglycerateReduced synthesis of hemoglobinLow levels of oxygen  <response>: Decreased production of 2,3-bisphosphoglycerate 2, 3 DPG is produced by an alternative pathway in glycolysis.If the glycolytic activity is decreased, the levels of 2,3 - DPG in RBCs will decrease.Decreased level of 2,3 - DPG causes:-Shifts the oxygen-hemoglobin curve to the leftIncreases the oxygen affinity of hemoglobin.
