Receptors generate a cellular response upon binding their specific ligand. This response can vary in magnitude. Desensitisation is a phenomenon in which activation of a receptor can reduce the magnitude of the response if it is subsequently activated again. Usually the longer a receptor is activated for the greater the desensitisation will be.
There are 3 general mechanisms as to how desensitisation occurs. The first is uncoupling of the receptor from proteins which generate the cellular response. The second is internalising receptors so that they cannot be activated. The third is reducing production of receptors so less are available. In general mechanism 1 is short term, 2 is mid-term and 3 is long term.

Which receives signals a fluid mosaic model or a receptor?
a receptor
How long does receptor activation take?
Receptor activation can happen within milliseconds to seconds when a ligand binds to the receptor, triggering a conformational change. The time it takes for the receptor to fully activate and initiate downstream signaling pathways can vary depending on the specific receptor and the cellular context.
Drugs that increase receptor activation are those that?
Drugs that increase receptor activation are known as agonists. They bind to the receptor and produce a biological response. This can lead to a variety of effects depending on the specific receptor and drug involved.
What is a channel linked receptor?
A channel linked receptor transduces functions of the same protein molecule. An example of a channel linked receptor are neurotransmitters in the brain.
What is controlled by the magnitude of a receptor potential?
The magnitude of a receptor potential determines the strength of the stimulus detected by the sensory receptor. A larger receptor potential indicates a stronger stimulus, while a smaller receptor potential indicates a weaker stimulus. This information is then transmitted to the central nervous system for further processing and perception.
What is the Problem of present generation of people?
desensitisation due to mass media exposure
Which receives signals a fluid mosaic model or a receptor?
a receptor
What are important tissue receptor tumor markers?
Important tissue receptor tumor markers include estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2) in breast cancer; epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK) in lung cancer; and the androgen receptor (AR) in prostate cancer. These markers help guide treatment decisions and predict response to targeted therapies.
Is CD4 an adhesion molecule?
The glycoprotein CD4 is a co-receptor. A co-receptor is "a cell surface receptor, which, when bound to its respective ligand, modulates antigen receptor binding or affects cellular activation after antigen-receptor interactions." (MediLexicon)
What is the receptor for equilibrium?
The Macula is the receptor for static equilibrium.
What is a molecule that acts as signal when it binds to a receptor?
Intracellular receptor
What receptor does aroma therapy stimulate?
What receptor is stimulated by aromatherapy
A protein on the cell membrane binds and recognized to specific substance is called a?
It is called a receptor protein.
How long does receptor activation take?
Receptor activation can happen within milliseconds to seconds when a ligand binds to the receptor, triggering a conformational change. The time it takes for the receptor to fully activate and initiate downstream signaling pathways can vary depending on the specific receptor and the cellular context.
What does the phrase density of receptor cells mean?
Density of receptor cells are the amount of receptor cells in a specific area of the body. This could be in the lips.
Drugs that increase receptor activation are those that?
Drugs that increase receptor activation are known as agonists. They bind to the receptor and produce a biological response. This can lead to a variety of effects depending on the specific receptor and drug involved.
What binds to a signal molecule enabling the cell to respond to the signal molecule?
A receptor protein on the cell membrane binds to the signal molecule, initiating a series of intracellular events that lead to a cellular response. The binding of the signal molecule to the receptor triggers a signaling cascade that ultimately activates specific cellular pathways.
