2. Consider the following nerve sequence. When nerve P is active, nerve P releases P. P activates P-receptors on nerve Q. When nerve Q is active, nerve Q releases Q. Q activates Q-receptors on cell G. When cell G is active, cell G releases Glop.P is removed from the space between nerve P and nerve Q by a transporter. Q is removed from the space between nerve Q and cell G by an enzyme that breaks down Q. 2a. Activating which receptor(s) P, or Q, IF ANY, would cause the release of Glop?
2b. Inhibiting which receptor(s) P, or Q, IF ANY, would cause the release of Glop? 2c. Activating the removal of which molecule(s), P or Q, IF ANY, would cause the release of Glop? 2d. Inhibiting the removal of which molecule(s), P or Q IF ANY, would cause the release of Glop? Do not worry about side effects, you just want the drug to lead to more Glop being released. Explain each answer concisely. 2. Consider the following nerve sequence. When nerve P is active, nerve P releases P. P activates P-receptors on nerve Q. When nerve Q is active, nerve Q releases Q.

Explanation / Answer
2a: Activation any of the P or Q receptor will cause release of the glop. ( activation of P receptor will cause it indirectly via release of Q, but activation of Q receptor will cuse the release directly.)
2b: Inhibiting any of the receptors will cause caessation of release of glop as the G cell activated via p and q receptor. But if P receptor is inhibited and q receptors remain activated then glop will be released.
2c. Activating removal of any subtance P or Q will not cause release of glop. If P is removed Q will not be activated and thus G will not be activated and glop will not release. again if Q is removed then G cell will not be activated and thus glop will not release.
2d. Inhibiting the removal of any substance P or Q will cause release of glop ( condition is that inhibiting the removal of one substance will not be coupled with initiation removal of other substance.)
