Flashcard 50: A researcher is studying role of glucose metabolites in normal cellular function. -In the experiment generating ATP are measured. -In these cells, glycolysis of a single glucose molecule always yields pyruvate but sometimes generates no net ATP. -What cell is most likely being studied in this experiment?

Answer: Erythrocytes because they love 2,3 bisphosphoglycerate because it's a main  regulator of oxygen transport in the body. when 2,3 bisphoglycerate are created ATP doesn't produce.
