Answer:

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.

When it comes to Colonial South America I would be reporting about the Indian tribes in rural Peru. The time period would be 19th century. Their lives are opressed under the Spanish Colonial rule. They are starting to assimilate, accepting Christianity which was a monotheistic religion. Before that period, they were worshiping many of their Mayan Gods and were living mainly form their own agricultural labor. Now, under the Spanish rule, they have to work for others sometimes in slave like conditions, for a very poor wage. Spanish Colonization of South America had a huge impact on the Indian Tribes. A lot of them were killed by desiese, were robbed of their gold and other possesions. They had to learn a new language and accept new cusoms. Even today a lot of them are exploited, working on coffee, salt and cocoa farms in harsh conditions for as little as 10$ a month.
