After the effector cell has been stimulated by acetylcholine (ach), what enzyme stops this stimulation and allows the effector membrane to repolarize?

a) decarboxylase
b) norepinephrine
c) acetylcholinesterase
d) catecholamine

The correct answer is C) Acetylcholinesterase.

Explanation:

Neurotransmitter release occurs in the neuron axon. The sending neuron has vesicles filled with neurotransmitters in their interior. When an action potential reaches the nervous terminal or the varicosities, it causes the neurotransmitter release by exocytose forward to the synaptic space. The molecule binds to its receptor in the postsynaptic neuron. This receptor is a protein structure that triggers an answer. As long as the acetylcholine is in the synaptic space, it keeps linking to its receptor and causing a postsynaptic answer. To stop this process, the neurotransmitter must be taken out from the synaptic space. There are two mechanisms by which the neurotransmitter can be eliminated:

the index of refraction of the second medium is higher. i just took the test trust me !

it's the cell cycle, but cytokines is when the cell divides.

theres 3 stages interphase,mitosis,and cytokines.

interphase prepares the cell for division.

mitosis is the process of dividing the cell,it has 4 parts interphase,anaphase,metaphase,and telophase.

lastly there's cytokines,that's when the cell divides into 2 daughter cells
