Up-regulation is where a cell creates more receptor due to little ligand activity. Down-regulation is the opposite. They are caused by intracelluar processes.
No, up-regulation involves an increase in the number of receptors on target cells in response to low hormone levels, which enhances the cell's sensitivity to the hormone. This helps the target cells respond more effectively to the hormone.
Down-regulation refers to the process by which a cell decreases the number of receptors on its surface in response to high levels of a specific signaling molecule. This reduces the cell's sensitivity to the signaling molecule.
The process that is made up of all the activities that help maintain an organism's homeostasis is called physiological regulation. This includes various mechanisms such as temperature regulation, hormone balance, and fluid balance to ensure internal stability in response to external changes.
The process you are referring to is known as negative feedback regulation. In negative feedback regulation, the product of a system acts to decrease its own production or activity, maintaining a balance within the system. This helps to prevent excessive build-up of the product and maintain stability in the system.
Adenosine builds up in the body when cells break down ATP (adenosine triphosphate) during energy production or when there is a decrease in blood flow or oxygen levels.
down regulation
prolonged exposure to high hormone concentrations desensitizes the target cells, so that they respond less vigorously to hormonal stimulation. This "down-regulation" involves loss of receptors and prevents the target cells from overreacting
Basically a pitch and a putt. If you miss the green you hit it onto the green- known as the up, then putt it in the hole- known as the down.
