2. Parkinson's disease is caused by a deficiency of dopamine in the substantia nigra of the brain. Dopamine is produced in the brain from L-DOPA (L-dihydroxyphenylalanine) by removal of a molecule of carbon dioxide. The L-DOPA is produced by oxidation of tyrosine, which is in turn produced from phenylalanine by another oxidoreductase. The enzyme that converts L-DOPA to dopamine is best e A. Oxidoreductase. I as an/a: B. Transferase. C. Hydrolase. D. Lyase. E. Isomerase. 1 200 Cevente
