Indicate whether each of the following statements relating to the body’s amino acid pool is true or false.

  1. a. Protein turnover contributes amino acids to the pool.
  2. b. The location for the pool is the liver.
  3. c. Synthesis of new protein requires withdrawal of amino acids from the pool.
  4. d. The pool contains all of the nonessential amino acids but none of the essential ones.

(a)

Interpretation Introduction

Interpretation: To identify whether the statement “protein turnover contributes amino acids to the pool” relating to the body’s amino acid pool is true or false.

Concept introduction: The total free amount of amino acid available for use in the body constitutes the amino acid pool. Dietary protein is one of the sources of the contribution of free amino acid to the amino acid pool. Dietary proteins upon complete degradation result in the formation of free amino acid which then enters into the amino acid pool. Amino acids present in the amino acid pool are used in 4 different ways in varying percentage.

Explanation of Solution

In the human body, the tissues undergo degradation and formation continuously. Degradation of proteins is effected by disease, injury and wear and tear...
