QUESTION 10 Why are the effects of the sympathetic nervous system so much more long lasting than parasympathetic? O epinephrine also acts a hormone and must be removed from circulation by the kidneys acetylcholine is very hard to break down and stays in the synapse for an extended period of time ◇ epinephrine is immediately destroyed in the synapse by enzymes acetylcholine cannot be removed from the synapse by reuptake into the neurons 5
