Receptor Activation

• How do receptors function in receiving neurotransmitters?

  They act like locks for specific neurotransmitter keys
• What are neurotransmitters released from?

  Presynaptic neurons
• What is receptor activation?

  Binding of neurotransmitter to receptors
• What happens when a neurotransmitter binds to a receptor?

  It triggers changes in the postsynaptic neuron
• What is synaptic transmission?

  Communication between neurons
• What happens to neurotransmitters after they are released?

  They diffuse across the synaptic cleft
• What happens during receptor activation?

  Neurotransmitter binds to postsynaptic receptors
• Why is receptor activation important?

  It is crucial for synaptic transmission
• How do binding sites on receptors function?

  They fit specific neurotransmitters like a lock and key
• Where do neurotransmitters bind after diffusion?

  Specific receptors on the postsynaptic neuron
• What is the process of selective binding in receptor activation?

  • Receptors accept specific neurotransmitters
  • Functions like a lock and key mechanism
• What is the role of receptor activation in synaptic transmission?

  Ensures precise communication between neurons
• What response does dopamine binding to its receptors trigger?

  Pleasure and reward responses
• What is the result of neurotransmitter binding to receptors?

  It initiates receptor activation
• What happens when neurotransmitters bind to receptors?

  It activates receptors and opens ion channels
• How do neurotransmitters interact with receptors on the postsynaptic neuron?

  They bind selectively to specific receptors
