Which of the following is not a step of action of nerve impulse? Correct Answer Guanosine monophosphate to guanine
“Guanosine monophosphate to guanine.” This is a part of the pathway of purine degradation by 5I – nucleotidase. Steps involved in action of nerve impulse are: • Release of acetylcholine during exocytosis into the synaptic cleft. • Activation of acetylcholine receptor by binding of 2 molecules of released acetylcholine which opens the channels of small cations such as Na+. • Production of muscle action potential due to inflow positively charged sodium ions. • Termination of acetylcholine by acetylcholine esterase which is attached to collagen fiber in extracellular matrix of synaptic cleft.
