Botulinum toxin causes flaccid paralysis mainly because it prevents:

hard

ACa2+ binding to troponin inside muscle fibers

Release of acetylcholine from the motor neuron terminal

CATP production in mitochondria of the muscle

DAction potentials in the spinal cord only

EFormation of tendons during development

Explanation

If ACh cannot be released, the muscle end plate is not activated, so no muscle action potential occurs and contraction fails (flaccid paralysis).
