agonists generally _______ activity at the synapse while antagonists generally ______ activity at the synapse.
ki77a [65]

Agonists activate the receptor thereby <u>increasing</u> activity at the synapse while antagonists generally prevent agonists from activating the receptors thereby <u>decreasing</u> activity at the synapse.

  • An agonist is the component that has the ability to increase the activity carried out by another substance.

  • The agonists work from their faculty of coupling to a cell-type receptor, in this way, they manage to generate a certain action in the cell.

  • The antagonists are the compounds that cause the opposite when they bind to the receptor, they cause a blockade by decreasing the activation of a synaptic receptor.

Therefore, we can conclude that agonists are compounds capable of increasing the action of synapse and blockers (antagonists) decrease activity at the synapse.
