  2. The drug ligand is the door that opens into the house, which is the neuron.
  3. The receptor protein is like a flame that ignites the stove, which is the drug ligand.
  4. The drug ligand works like a comforter, providing a protective cover for the receptor protein.

Answer to Question 1

Answer: 1
Explanation: Like a key (drug ligand molecule) fitting into a lock (receptor protein in the neuron cell), the drug molecule ligand tells the protein receptor in the neuron cell to do something (open the gate). The other images (door into a house, flame on a stove, comforter on a bed) do not convey the interaction of the ligand and receptor that results in specific activity.

Answer to Question 2

Answer: 2, 3, 4, 5
Explanation: High blood pressure can open the BBB. Radiation, infection, and brain injury also can open the BBB. The progression of dementia causes a weakening of the BBB. Anxiety has not been associated with BBB vulnerability.
