Chapter 18 Reading Question 10

Part A

Since all organs degrade amino acids, which leads to the production of ammonia, which of the following statements regarding the fate of ammonia is NOT correct?

Since all organs degrade amino acids, which leads to the production of ammonia, which of the following statements regarding the fate of ammonia is NOT correct?

In the liver, alanine is converted to pyruvate at the same time -ketoglutarate is converted to Gln; the Gln is deaminated to Glu, and the resulting NH4 is converted to urea. Most tissues convert ammonia directly to urea. Some tissues use glutamine as the carrier form of ammonia. In muscle, glutamate is converted to -ketoglutarate acid while also producing alanine, which is used as the ammonia carrier to the liver.

Explanation / Answer

Answer=

Part A

Since all organs degrade amino acids, which leads to the production of ammonia, the following statements regarding the fate of ammonia is NOT correct

In muscle, glutamate is converted to ?-ketoglutarate acid while also producing alanine, which is used as the ammonia carrier to the liver.

Explaination= alanine transaminase has an important function in the delivery of skeletal muscle carbon & nitrogen in the form of alanine to the liver

In the glucose -alanine cycle ammonium ion is transported from muscle cells to the liver in the form of alanine

trough glycolysis ,glucose becomes pyruvate in the muscle .pyruvate producing alanine & is transported to the liver
