The statement/s which are true about antagonists from the following is/are: A. They bind to the receptor site. B. Get transferred inside the cell for their action. C. Inhibit the natural communication of the body. D. Mimic the natural messenger. Choose the correct answer from the options given below:
The question requires us to identify which statements are true about antagonists from the given options. To solve this, we need to understand the role of antagonists in biochemistry or pharmacology.
Statement A: They bind to the receptor site. Antagonists are molecules that bind to receptors but do not activate them. Instead, they block receptor activity by preventing natural activators (agonists) from binding. Thus, this statement is true.
Statement B: Get transferred inside the cell for their action. Generally, antagonists do not need to enter the cell to exert their effects. They act by blocking receptors, which are frequently located on the cell membrane. This statement is false.
Statement C: Inhibit the natural communication of the body. Since antagonists block receptors from binding with agonists, they effectively inhibit natural signaling pathways and communication in the body. Therefore, this statement is true.
Statement D: Mimic the natural messenger. Antagonists do not mimic natural messengers. Instead, they hinder the action of such messengers by blocking receptor sites. This statement is false.
Based on this analysis, the true statements about antagonists are A and C.
Therefore, the correct answer is: A and C.
It is important to remember that antagonists are critical in pharmaceutical applications, where they are used to block overactive physiological pathways, thereby helping to treat various conditions.
