A newborn child has convulsions that have been observed after prescription of vitamin B6. This most probable cause of this effect is that vitamin B6 is a component of the following enzyme:
- A. Ketoglutarate dehydrogenase
- B. Glycogen phosphorylase
- C. Aminolevulinate synthase
- D. Glutamate decarboxylase
