Which catecholamine is made by the action of tyrosine hydroxylase and aromatic amino acid decarboxylase? (assume that a biologically relevant molarity of all substrates for both tyrosine hydroxylase and aromatic amino acid decarboxylase are available.)

Catecholamine made by the action of tyrosine hydroxylase and aromatic amino acid decarboxylase is DOPAMINE

Explanation:

Catecholamines are formed from the amino acid - tyrosine. Food which are rich in protein are sources of Tyrosine. Also, the body system can produce tyrosine by adding hydroxyl group -OH to phenylalanine. Cells that secret catechomines such as dopamine use several reactions (catalyzed by tyrosine hydroxylase and amino acid decarboxylase) to convert tyrosine in series to L-DOPA and then to dopamine. L-DOPA is L-3,4-dihydroxyphenylalanine. The enzyme - tyrosine hydroxylase changed tyrosine to L-DOPA. While L-DOPA is changed into dopamine by the enzyme - amino acid decarboxylase.

the first settlements began along the huang river because of the importance of the huang river in the beginning of china. it goes back to the story, “the tale of emperor yu”, which references the tale of the great flood, which was caused by the huang river and was believed to create and influence china’s making.
