Nikitich [7]
Enzymes are made of strings of amino acids chemically bonded to one another. These bonds give each enzyme a unique structure, which determines its function. They mostly break down carbohydrates and fats. Once a protein source reaches your stomach, hydrochloric acid and enzymes called proteases break it down into smaller chains of amino acids. Amino acids are joined together by peptides, which are broken by proteases.

A client whose parkinson's disease is being treated with tolcapone should concurrently take what drug?
steposvetlana [31]

Answer:

The correct answer would be levodopa/carbidopa.

Tolcapone is a drug used as an adjunct to levodopa/carbidopa combination medication.

These drugs are used to treat the symptoms of Parkinson's disease.

Tolcapone is used to inhibit enzyme COMT (catechol-O-methyl transferase).

In the brain, levodopa is converted into dopamine which helps in controlling the movement.

Carbidopa helps in preventing the breakdown of levodopa in the blood which allows more levodopa to enter the brain. In addition, it helps in reducing the side-effects associated with levodopa such as vomiting, nausea et cetera.
