(a)
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.
(b)
Interpretation: To identify whether the statement “the location for the pool is the liver” 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.
(c)
Interpretation: To identify whether the statement “synthesis of new protein requires the withdrawal of amino acids from 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.
(d)
Interpretation: To identify whether the statement “the pool contains all of the nonessential amino acids but none of the essential ones” 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.
