Question
Which of the following correctly pairs the enzyme with the type of reaction it catalyzes in amino acid/nitrogen metabolism?Group of answer choicesbranched chain alpha keto acid dehydrogenase complex: oxidative decarboxylationaspartate aminotransferase: hydrolysisnitrate reductase: isomerasephosphoserine phosphatase: oxidation/reductionphosphoglycerate dehydrogenase: transamination
Solution
The correct pairing of the enzyme with the type of reaction it catalyzes in amino acid/nitrogen metabolism is:
Branched chain alpha keto acid dehydrogenase complex: Oxidative decarboxylation
Explanation:
-
Branched chain alpha keto acid dehydrogenase complex: This enzyme complex is involved in the oxidative decarboxylation of branched chain amino acids. This is a process where a carboxyl group is removed from the amino acid, releasing carbon dioxide in the process.
-
Aspartate aminotransferase: This enzyme is involved in the transamination reaction, not hydrolysis. It transfers an amino group from aspartate to a keto acid.
-
Nitrate reductase: This enzyme is involved in the reduction of nitrate to nitrite, not isomerization.
-
Phosphoserine phosphatase: This enzyme is involved in the hydrolysis of phosphoserine to serine, not oxidation/reduction.
-
Phosphoglycerate dehydrogenase: This enzyme is involved in the oxidation of 3-phosphoglycerate to 3-phosphohydroxypyruvate, not transamination.
