What else can I help you with?
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 specific cells in the body to which hormones convey information?
Hormones convey information to target cells in the body. These cells have specific receptors that can bind to the hormone molecules, triggering a response or a change in cellular activity. Target cells are typically found in tissues or organs that are affected by the hormone.
What are the structures that allow hormones to bind to their target cells?
Hormones bind to specific protein receptors on the surface or inside target cells. These receptors are typically found on the cell membrane or in the cytoplasm. Once the hormone binds to its receptor, it triggers a signaling cascade that leads to specific cellular responses.
The reason only certain cells are affected is that the membranes of these cells have specific?
receptors
Where are the hormone receptors for nonsteroid hormones located?
The hormone receptors for nonsteroid hormones are primarily located on the cell membrane of target cells. These receptors are often proteins that bind to the hormone and initiate a signaling cascade within the cell. This process allows nonsteroid hormones, which are typically water-soluble, to exert their effects without entering the cell. Examples of nonsteroid hormones include peptide hormones like insulin and catecholamines like epinephrine.
How do you some hormones affect only certain cells in the body but not others?
These cells have specific types of receptors on their membranes.
Why do hormones stimulate specific cells?
Hormones stimulate specific cells because they bind to specific receptors that are uniquely present on those target cells. This receptor-hormone interaction triggers a series of cellular responses, leading to the desired physiological effect. The specificity of hormone action ensures that only the appropriate cells respond to the hormone, allowing for precise regulation of various bodily functions. Additionally, the distribution of hormone receptors throughout the body dictates which cells will be affected by a particular hormone.
What is the method that tropic and nontropic hormones produce response?
Tropic hormones act by stimulating the release of other hormones from target glands, which in turn produce a physiological response. Nontropic hormones directly bind to receptors on their target cells to initiate a cellular response without involving other hormones.
What do hormones bind to on the surface of target cells?
Hormones typically bind to specific protein receptors located on the surface of target cells. These receptors are responsible for initiating a signaling pathway within the cell in response to the hormone binding, leading to specific cellular responses.
Which statement best explains why some cells in the reproductive system only respond to certain hormones?
As with any cellular signal, only cells that are expressing receptors on their cell surface for a particular signal will be effected. In the case of your question, only cells in a womens body that are expressing specific receptors for reproductive hormones will respond to those hormones. How some cells know to have receptors and others do not is a mystery to science still. It is likely determined by a combination of environmental and genetic cues during development.
Hormones attach to plasma membrane proteins called?
Hormones attach to plasma membrane proteins called receptors. These receptors can trigger signaling pathways within the cell when activated by the hormone binding.
What are target cells.?
In your body, you have certain cells that can receive and process hormones released by your pituitary gland, hypothalamus and other endocrine glands. However, not all cells can receive all hormones. Target cells are cells that have receptors on them for a specific hormone. So a target cell may have a receptor for GH hormone, thus allowing GH to be absorbed by only the target cells with GH receptors.
