    A neurotransmitter ATP pump
  • b)
    A phagocytosis-inducing protein
  • c)
    A sodium-neurotransmitter symporter
  • d)
    A neurotransmitter channel
Correct answer is option 'C'. Can you explain this answer?

Selective serotonin reuptake inhibitors (SSRIs) work by blocking the reuptake of serotonin, a neurotransmitter, in the pre-synaptic neuron. They specifically target and block the serotonin transporter protein, which is a sodium-neurotransmitter symporter. This protein is responsible for the reabsorption of serotonin from the synaptic cleft back into the pre-synaptic neuron. By blocking this transporter, SSRIs increase the concentration of serotonin in the synaptic cleft, allowing it to interact with and stimulate the post-synaptic receptors for a longer period of time. This helps alleviate symptoms of depression and improve mood.
