Final answer:
Arginine (B) is the amino acid that is believed to stimulate the production of growth hormone, which is crucial for body growth and protein synthesis.
Step-by-step explanation:
The amino acid which is purported to stimulate the growth hormone production is Arginine (B).
Growth hormone (GH), produced by the anterior pituitary gland, plays a critical role in body growth, protein synthesis, and cellular replication. It does so through both direct and indirect mechanisms. The indirect mechanism involves insulin-like growth factors (IGFs) or somatomedins, which are proteins produced by the liver that stimulate the uptake of amino acids and promote tissue growth. Moreover, GH is known to stimulate protein synthesis, enhance amino acid uptake by the cells, and support the retention of various minerals. It also promotes lipolysis which leads to the use of fat as an energy source.
