Title: Re: What steps are necessary to terminate neurotransmitter action? What would happen Post by: duddy on Nov 4, 2011 Neurotransmitter molecules are either enzymatically degraded or are taken back into the presynaptic terminal (reuptake). Calcium ions are removed from the axon terminal. Failure of these steps prolongs the action of the neurotransmitter. Consequences vary according to the identity of the effector organ. In a skeletal muscle, for example, this can lead to spastic paralysis.
