WebMar 29, 2024 · Pyruvate kinase is an enzyme that helps cells turn sugar (glucose) into energy (called adenosine triphosphate, ATP) in a process called glycolysis. Red cells rely on this process for energy, and so, pyruvate kinase deficiency leads to a deficiency in energy and to premature red cell destruction (hemolysis). WebMar 20, 2024 · Red Blood Cells (RBCs), on the other hand, are highly differentiated cells with a very short lifespan. They are replaced in humans approximately every two weeks. RBCs are enucleated and do not have mitochondria, and thus, only generate ATP through the process of glycolysis. the HKI protein is free floating in the cytoplasm in this system.
