Quizplus · Accepted Answer

Acetylcholine (ACh) is synthesized from choline, which comes from dietary fats, and acetyl coenzyme A. The enzyme choline acetyltransferase acts on these two substances to produce ACh. Option A is not correct as choline is not formed by the actions of mitochondria within cells but is obtained from the diet. Option C is incorrect as ACh is not synthesized from the amino acid tyrosine. Option D is incorrect as tryptophans are not involved in the synthesis of ACh.
