Question

Explain why it is important for the neurotransmitter substance to be deactivated

Answer 1

Once in the synapse, it must be removed quickly or chemically inactivated to avoid constant attention of the post-synaptic cell and excessive firing of action potentials.

What is a neurotransmitter?

• A neurotransmitter is a key molecule that a neuron secretes to affect another cell across a synapse.
• The cell that receives the signal, which could be any major body part or target cell, could be another neuron or gland, or muscle cell.
• Neurotransmitters are released from synaptic vesicles into the synaptic cleft and interact with neurotransmitter receptors on target cells.
• After being recognized by a post-synaptic receptor, a neurotransmitter molecule is released into the synaptic cleft.
• Once in the synapse, it must be removed quickly or chemically inactivated to avoid constant attention of the post-synaptic cell and excessive firing of action potentials.

Therefore, once in the synapse, it must be removed quickly or chemically inactivated to avoid constant attention of the post-synaptic cell and excessive firing of action potentials.
