Explanation:Cells typically up or down regulate depending on the concentration of a hormone levels. When there is a excessive concentration of a hormone in the blood stream, the cell decreases the number of receptors reducing the interaction with that hormone, Also, when there is excessive hormone reduction, the target cells activate to increase their number of receptors.
Down regulation occurs by the the deactivating or degrading of target cells to reduce the number of receptors due to their sensitivity to a particular excess hormone.
