The glucose-alanine cycle is a method of transferring ammonia from the skeletal muscle to the liver. in this process the non-toxic carrier of ammonia is which of the following compounds?
(a) alanine
(b) arginine
(c) pyridoxal phosphate (plp)
(d) enteropeptidase

The correct answer will be option-A.

Explanation:

The ammonia in a cell at its pH exists in the form of ammonium ions which if present in excess can cause coma. So, ammonium ions have to be transported to either liver or kidney where they are utilized to form urea and excreted out respectively.

The ammonia from muscle cells is transferred via a process called glucose-alanine cycle which transports the ions in the form of alanine which is formed by the conversion of pyruvate to alanine via transaminase reaction.

Thus, option-A is the correct answer
