<prompt> In aluminium phosphide poisoning, not true is:Accumulation of acetylcholine at NM junctionCytochrome oxidasePhosphine formationMetabolic acidosis  <response>: A i.e. Accumulation of acetyl choline at NM Junction - Celphos or Aluminium phosphide, on coming in contact with moisture liberates phosphineQ, which on reacting with silver nitrate AgNO3 gives black colour Breath test.
