What happens when an agonist, instead of the endogenous (natural) hormone, binds to the hormone receptors of a target cell? a. The agonist blocks any response in the target cell b. Transcription factors are blocked from binding to the promotor region c. An antagonist is necessary to remove the agonist d. The cell responds by producing its own hormone e. The agonist has the same effect as the endogenous hormone
What happens when an agonist, instead of the endogenous (natural) hormone, binds to the hormone receptors of a target cell?
| a. |
The agonist blocks any response in the target cell |
|
| b. |
Transcription factors are blocked from binding to the promotor region |
|
| c. |
An antagonist is necessary to remove the agonist |
|
| d. |
The cell responds by producing its own hormone |
|
| e. |
The agonist has the same effect as the endogenous hormone |
Hormones are chemical messengers that interface with receptors present on the outside of a cell membrane or with receptors that are situated inside the cell, in the cytoplasm (cytoplasmic receptors). This cooperation offers the impacts hormones apply on target cells and organs.
An agonist is a substance that attaches to a receptor and actuates the receptor to deliver a biological reaction. While an agonist causes an activity, an antagonist obstructs the activity of the agonist and an antagonist causes an activity inverse to that of the agonist.
An agonist is a substance that attaches to a receptor and actuates the receptor to deliver a biological reaction. Antagonists block any response in the target cell. Hence the option a is incorrect.
Agonist induces biological response in the targeted cell. Therefore transcription factors are active and bind to the promoter region. Hence the option b is incorrect.
An antagonist helps in removing agonist from the target cell receptors. Hence the option c is correct.
After the agonist binds the target cell it induces a response like producing hormone. Hence the option d is correct.
Agonist has the same effect as that of the endogenous hormone. Hence the option e is correct.
