Which of the choices below is not a factor required for target cell activation by hormone receptor interaction?
Protein synthesis is not a factor required for target cell activation by hormone receptor interaction. The essential factors include binding of the hormone to its receptor, conformational changes in the receptor, and activation of intracellular signaling pathways.
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 determines what cell a hormone will effect?
The target receptor proteins of cells will cause them to affected by a specific protein. These cells are also called "target" cells. Hormones flow via the bloodstream throughout the entire body, but they only affect their specific "target" cells.
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.
What is the difference between Target cells and non-target cells?
Target cells are cells that have specific receptors for a hormone or external signal, allowing them to respond to the signal. Non-target cells do not have receptors for the hormone or signal, so they do not respond to it. Target cells are the primary sites of action for hormones, while non-target cells are unaffected by the hormone.
Which of the choices below is not a factor required for target cell activation by hormone receptor interaction?
Protein synthesis is not a factor required for target cell activation by hormone receptor interaction. The essential factors include binding of the hormone to its receptor, conformational changes in the receptor, and activation of intracellular signaling pathways.
A nonsteroid hormone enters a target cell by passing across its cell membrane?
The nonsteroid hormone binds to a receptor on the cell membrane, triggering a signaling cascade inside the cell without needing to enter the cell itself. This cascade leads to various cellular responses and changes in gene expression. This mechanism allows for rapid and precise cellular responses to the hormone signal.
How does a nonsteroid hormone act on its target cells?
They bond to receptor sites on their target cells to facilitate some reaction, depending on the hormone. For example, insulin is a protein hormone that bonds on receptor sites on muscle cells to allow the diffusion of glucose into the muscle cell. Without insulin, the cell membrane is impermeable to glucose, but the insulin bridge made when the hormone bonds with receptors on the muscle cell membrane allows for the glucose to pass through. This is called facilitated diffusion.
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.
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.
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.
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 is a Specific structure that responds to a particular hormone?
The structure is called a hormone receptor. It is a protein located on the surface or within a cell that binds to a specific hormone, triggering a cellular response.
What determines what cell a hormone will effect?
The target receptor proteins of cells will cause them to affected by a specific protein. These cells are also called "target" cells. Hormones flow via the bloodstream throughout the entire body, but they only affect their specific "target" cells.
What is the target for ACTH?
ACTH means adrenocorticotrophic hormone. The target for this hormone is adrenal gland. It stimulate the gland to produce the corticosteroid hormone.
A steroid hormone acts on a target cell by?
binding to a specific receptor located inside the cell. This hormone-receptor complex then enters the nucleus and binds to specific DNA sequences, regulating the expression of target genes. This can lead to changes in protein synthesis and cellular function in the target cell.
What is found in or on a hormone's target cell?
Hormone receptor
