Question
A competitive antagonist is a substance that:a.Binds to one receptor subtype as an agonist and to another as an antagonistb.Binds to the nonspecific sites of tissuec.Binds to the same receptor site and progressively inhibits the agonist responsed.Interacts with receptors and produces submaximal effect
Solution
A competitive antagonist is a substance that: c. Binds to the same receptor site and progressively inhibits the agonist response.
Here's why: A competitive antagonist is a type of drug that binds to the same receptor as the agonist but does not activate it, instead it blocks the agonist from binding to the receptor. This results in a decrease in the agonist's effect. The binding of the antagonist is reversible, and its inhibitory effect can be overcome by increasing the concentration of the agonist. Hence, it progressively inhibits the agonist response.
