Question

Quizplus · Accepted Answer

Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) are enzymes that are mainly found in liver cells. When liver cells are damaged, these enzymes are released into the bloodstream, leading to abnormally high levels in the blood, indicating liver disease. COX-1 and COX-2 are enzymes involved in the production of prostaglandins, which are not specific for liver disease. Glucokinase, glucose-6-phosphotase, pyruvate dehydrogenase, phenylalanine hydroxylase, and transaminase are not specific for liver disease either.
