Answer:
Presynaptic reuptake transporters are a major method of inactivation for Serotonin and GABA. Option B. These molecular transport systems are found on the nerve terminal of the presynaptic neuron.
Presynaptic reuptake transporters inactivate Serotonin and GABA by reuptaking these neurotransmitters into the presynaptic neuron, which effectively ends their activity at the synapse.
While Histamine and Neuropeptides also need to be inactivated, they use other methods for this process.
They play a crucial role in the process of neurotransmitter reuptake, which is a key mechanism that ends the action of neurotransmitters at the synapse.
The neurochemicals in the synaptic cleft are taken back up into the presynaptic neuron, thereby lowering their concentration in the synapse and effectively reducing their activity.
This process is vital for the transmission of signals in the nervous system and maintaining stable neural activity. Neurotransmitters such as Serotonin and GABA use this method, while Histamine and Neuropeptides use other methods for their inactivation.
Hence, the correct answer is Option B.
