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). WebThe pathway is especially important in red blood cells (erythrocytes). There are two distinct phases in the pathway. The first is the oxidative phase, in which NADPH is generated, ...
