Question

Botulinum toxin binds to receptors present at the axon terminal in order to enter the neuron

Answer 1

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.

Answer 2

Botulinum toxin does not bind to receptors presemt at the axon terminal in order to enter the neuron. It is a neurotoxin protein produced by Clostridium botulinum which is a bacterium. It prevents the release of neurotransmitter from axon endings that results to flaccid paralysis.
