3) Which of the following statements is consistent with protein catabolism in the FED state?

A. Glutaminase activity in the liver will be low

B. Amino acids will be used as a substrate for gluconeogenesis

C. The conversion of alpha-ketoglutarate to glutamate will be favored in the liver

D. High levels of arginine will stimulate the activity of urea synthesis

(I’m thinking A or C?)

I have narrowed the following question to 2 possible answers. I would really appreciate an expert’s help on which one is correct. Thank you.

Explanation / Answer

In the fed state the glutaminase activity wil be low in the liver because glutaminase is the enzyme which lyse the Glutamine in to glutamate, pyruvate,co2 and aspartate. Since in the fed state there is less demand of pyruvate which is anyway coming from the glycolysis thats why glutaminase activity will be less
