Congenital non-spherocytic haemolyic anaemia (CNSHA) is caused by a mutation of one or more of the enzymes of the glycolytic pathway. The most common is a mutation in the gene for pyruvate kinase resulting in a non-functional enzyme. Patients with CNSHA often show marked ATP deficiencies. Given what you know about this enzyme’s action, why would this be expected?
a. Pyruvate kinase produces ATP when it phosphorylates glucose to glucose-6-phosphate. b. Pyruvate kinase uses excess ATP when it phosphorylates fructose-6-phosphate. c. Pyruvate kinase produces ATP when it generates pyruvate from phosphophoenolpyruvate (PEP). d. Pyruvate kinase uses excess ATP when it catalyzes the dehydration of 2-phosphoglycerate.
