What is found in or on a hormone's target cell?
Hormone receptor
What hormones has more target cells in the body than any of the others Antidiuretic hormone corticotropin releasing hormone growth hormone or oxytocin?
Growth hormone has more target cells in the body than any of the others mentioned. It acts on many tissues throughout the body to stimulate growth, cell reproduction, and regeneration.
What cell determine cell activities?
The binding of a hormone to a receptor is the first step. Target cell activation by hormone-receptor interaction depends equally on 3 factors. First the blood levels of the hormone, second ,relative numbers of receptors for that hormone on or in the target cells and the third ,strength of the binding between the hormone cell and the receptors.
What hormones has more target cells in the body than any of the others Antidiuretic hormone corticotropin-releasing hormone growth hormone or oxytocin?
Growth hormone has more target cells in the body than any of the others listed. It acts on various tissues and organs to regulate growth, metabolism, and cell regeneration throughout the body.
Where is the receptor for cortisol found?
Receptors of protein hormones are present in plasma membrane but for steroid hormones no membrane receptors are needed as they can enter cell membrane , mobile receptors pic steroid hormones from cell membrane and carry them to nucleus .
How does a hormone identify its target?
Only target cells have receptors inside cytoplazm (for steroid hormones) or on cell membrane (for protein hormones) that make the hormone active.
Thyroid hormone enters target cells in a manner similar to?
Thyroid hormone enters target cells through facilitated diffusion, where it moves across the cell membrane with the help of specific transporter proteins. Once inside the cell, thyroid hormone binds to nuclear receptors, affecting gene expression and regulating cellular metabolism.
What is the difference between receptors for steroid hormones and Peptide hormone?
Peptide based hormones exert their effects on a cell by way of second messengers (cAMP or PIP) pathways. Steroid based hormones exert their effects on a target cell via direct gene activation.
What is found in or on a hormone's target cell?
Hormone receptor
Where would steroid hormones most likely interact with their target cell?
Steroid hormones typically interact with their target cells inside the cell, specifically in the cytoplasm or nucleus. Once inside, they bind to specific receptor proteins, forming hormone-receptor complexes that can then modulate gene expression and alter cellular processes.
How do hormone and target cell recognize one another?
Hormones are specific molecules released by endocrine glands into the bloodstream. Each hormone binds to a specific receptor protein on the surface of the target cell. The receptor protein acts like a lock and key, ensuring that only the specific hormone can bind and trigger a cellular response in the target cell.
Steroid hormones enter the bloodstream by diffusion and?
Steroid Hormones only enter the bloodstream by diffusion. If you are a student taking anatomy/phyiso 2 and refering to this question: All steroid hormones are derived from (cholesterol). Which steroid hormone is produced is determined by the (enzymes) present in the cell. The common precursor molecule for all steroid hormones is (pregnenolone). Steroid hormones enter the blood stream by (diffusion) and (do) require a carrier. The rate of secretion of steroid hormones is (slower) then catecholemines because steroid hormones are not (stored). Hope that helps-
What recognize a hormone's chemical structure?
A target cell is a cell in the body that recognizes a hormone's chemical structure. It is a cell to which a hormone binds chemically.
Are hormones target molecules or signal molecules?
Hormones affect target cells because target cells have receptors that bind with certain hormones (they're specific). If a cell does not have a receptor then it is not affected by hormones. Target cells (which do have the receptor for a particular hormone) would be affected by the hormone.
Hormone and receptor interactions are based on?
Hormone and receptor interactions are based on specific binding between the hormone and its receptor. The receptor acts as a target for the hormone, triggering a series of cellular responses once bound. This interaction is highly specific, allowing for precise signaling within the body.
What hormones has more target cells in the body than any of the others Antidiuretic hormone corticotropin releasing hormone growth hormone or oxytocin?
Growth hormone has more target cells in the body than any of the others mentioned. It acts on many tissues throughout the body to stimulate growth, cell reproduction, and regeneration.
What is the machaism of steroid hormone cascade pathway?
The steroid hormone cascade pathway begins when a steroid hormone, such as cortisol or estrogen, diffuses through the cell membrane and binds to its specific intracellular receptor. This hormone-receptor complex then translocates to the nucleus, where it binds to specific DNA sequences, regulating the transcription of target genes. This process ultimately leads to the synthesis of proteins that mediate various physiological responses. The pathway is characterized by its relatively slow onset of action, as it involves changes in gene expression and protein synthesis.
