A) acetylcholine
B) atropine
C) cholinesterase
D) serine
Correct Answer: A
Solution :
[a] Acetylcholine released from an excited terminal axon, depolarises the membrane and is then very rapidly inactivated by the enzyme cholinesterase, which is present in great concentrations in the neuromuscular junction. The inhibition of cholinesterase will result in the muscle being unable to restore the state of polarisation.You need to login to perform this action.
