Question

Which of the following enzyme changes the aspartate to oxaloacetate?

• A. Malate dehydrogenase
• B. Aspartate transaminase
• C. Hexokinase
• D. All of the above

Answer 1

The correct option is B Aspartate transaminase

Aspartate transaminase enzyme is also called as AST or aspartate aminotransferase or serum glutamic oxaloacetic transaminase (SGOT). It changes the aspartate to oxaloacetate and vice versa. Simultaneously, it converts alpha- ketoglutarate to glutamate and vice versa.

Aspartate (Asp) + alpha-ketoglutarate <--> oxaloacetate + glutamate (Glu).

Thus, the correct answer is 'Aspartate transaminase.'
