Reuptake, or re-uptake, is the reabsorption of a neurotransmitter by a neurotransmitter transporter of a pre-synaptic neuron after it has performed its function of transmitting a neural impulse.
Reuptake is necessary for normal synaptic physiology because it allows for the recycling of neurotransmitters and regulates the level of neurotransmitter present in the synapse and controls how long a signal resulting from neurotransmitter release lasts. Because neurotransmitters are too large and hydrophilic to diffuse through the membrane, specific transport proteins are necessary for the reabsorption of neurotransmitters. Much research, both biochemical and structural, has been performed to obtain clues about the mechanism of reuptake.
What else can I help you with?
What do neurotransmitters open?
Neurotransmitters act on synapses.
What neurotransmitters are amino acids?
define amino acids in neurotransmitters
Which structure in the body releases neurotransmitters?
Neurons release neurotransmitters.
What does an axon release when an impulse reaches the end of it?
Neurotransmitters to the synapse and the neurotransmitters bind with the receptors releasing the second messengers.
What releases neurotransmitters into the synapse?
Neurotransmitters are released into the synapse by the presynaptic neuron.
Are neurotransmitters that depress the resting potential called excitatory?
No, neurotransmitters that depress the resting potential are called inhibitory neurotransmitters. Excitatory neurotransmitters have the opposite effect, causing depolarization and increasing the likelihood of an action potential.
Certain mental problems are thought to be caused by not having enough neurotransmitters. Why would a lack of neurotransmitters cause problems?
Neurotransmitters send signals from neuron to neuron
What is the opposite of dopamine in terms of neurotransmitters?
The opposite of dopamine in terms of neurotransmitters is serotonin.
From where are neurotransmitters secreted?
Neurotransmitters are secreted from the axon terminals of neurons in the brain and nervous system.
What is it called when neurotransmitters are recycled?
The process of recycling neurotransmitters is known as reuptake. This is when neurotransmitters are taken back up into the presynaptic neuron after they have been released into the synaptic cleft.
What are neurotransmitters that affect a neuron's response to other neurotransmitters called?
These are typically known as neuromodulators; they can either change the rate at which a neurotransmitter is released, or alter the response to a certain neurotransmitters.
Are there neurotransmitters in our intestines and organs?
Yes, neurotransmitters are found wherever nerves are found.
