The Botulinum toxin is a neurotoxins produced by the Clostridium botulinum. This toxin bind to the neuron presynaptically and by the exocytosis it enters in the neuron. It has a greater affinity to Cholinergic receptors as compared to the acetylcholine. Hence, the toxin causes the decrease in the release of the acetylcholine molecules.
As a result of the decreased in the release of the acetylcholine the neuro-transmission is blocked, and due to this the person dies.
Hence, the given statement is true.
