Hormones affect specific tissues called?
Hormones affect specific tissues called target tissues or target cells. These tissues have receptors that bind to hormones, triggering a response or change in cellular activity.
The signaling chemicals produced by one group of cells that affect distant target cells are called?
hormones.
explain why hormones in the bloodstream are able only to affect target cells/organs and not other cells/organs?
Hormones in the bloodstream are able to affect target cells/organs and not other cells/organs because of selective permeability. This means that hormones are only able to pass through the cell membrane of certain cells and organs, and not through the cell membrane of other cells and organs. The cell membrane of the target cells and organs are specialized to allow the hormones to pass through, while the cell membrane of other cells and organs are not specialized and are therefore impermeable to the hormones. This is due to the presence of receptor proteins on the cell membrane of the target cells and organs. These receptor proteins can bind to the hormones and facilitate their entry into the cell. Since these receptor proteins are not present on the cell membrane of other cells and organs, the hormones are unable to bind to them and therefore unable to cross the cell membrane. In addition, hormones can be broken down by enzymes in the bloodstream, which means they can’t reach their target cells and organs if they are exposed to the enzymes. This further ensures that hormones only affect the target cells and organs, and not other cells and organs. In summary, hormones in the bloodstream are able to affect target cells and organs and not other cells and organs because of selective permeability and the presence of receptor proteins on the cell membrane of the target cells and organs. Other cells and organs do not have these specialized receptor proteins and therefore cannot be affected by the hormones.
Are peptide hormones water soluble?
Yes, peptide hormones are generally water soluble. This makes it easier for them to be transported in the bloodstream and to interact with their target cells or receptors which are often located on cell membranes.
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 Peripheral cells sensitive to the presence of hormones are called?
Target Cells
What is the difference between plant hormones and animal hormones?
The plant hormones different parts of the plants in a different way while the animal hormones affect the target cells in more than one organ.
Where do glands send messages to target cells?
Glands send messages in the form of hormones to target cells through the bloodstream. Hormones are released by glands into the blood where they travel to target cells throughout the body to elicit a specific response. Target cells have specific receptors that recognize and respond to the hormones.
How do circulating hormones differ from paracrines and autocrines with reference to their target cells?
Circulating hormones are secreted into the bloodstream and can affect target cells in distant parts of the body, whereas paracrines act on nearby cells and autocrines act on the same cell that produced them. Hormones travel through the bloodstream to reach their target cells, while paracrines and autocrines act locally without being transported through the bloodstream.
How do hormones interact with target cells?
penis
Where do hormone go?
hormones go to there target cells or target organs
Why are hormones able to affect only certain cells and not other cells?
Because they only activate target cells that have special receptors that only work when that specific hormone attaches to it.
