Question

Twenty-four hours after removing the liver of a mammal the concentrations of urea and amino acids in the blood would be changed in which of the following ways?

• A. Both urea and amino acid levels would have risen
• B. There would be no change in the level of either
• C. The amino acid level would have risen while the urea level would have fallen
• D. The urea level would have risen while the amino acid level would have fallen

Answer 1

Answer: (C)

The amino acid level would have risen while the urea level would have fallen

Urea is produced in the liver which is a breakdown product of amino acids if the liver is removed amino acids will not be metabolized and urea level will rise.

So, the correct option is 'The amino acid level would have risen while the urea level would have fallen'.
