Does up-regulation involve the loss of receptors and prevents the target cells from overreacting to persistently high hormone levels?
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.
What term does down-regulation refer to?
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.
What is the process that is made up of all the activities that help maintain an organism's homeostasis?
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 by which the product of a system shuts down the system or limits its operation is called the inhibition?
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.
What is it called when a hormone is present in excessive levels the number of target cells receptors may decrease?
Downregulation is the process in which the number of target cell receptors decreases in response to excessive levels of a hormone. This can help maintain homeostasis by reducing the cell's sensitivity to high hormone levels.
What kind of regulation is release of epinephrine from the adrenal medulla?
down regulation
Sometimes prolonged excessive exposure to high hormone concentrations causes a phenomenon known as?
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
What does up and down mean in golf?
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.
What causes a bicycle to speed up going down hill?
gravityGRAVITY
When you lay down and look up you get dizzy what causes that?
ear infection
What causes a lawn mower engine to constantly rev up and down?
Revving up and down is usually a symptom of a dirty air filter.
Are deregulation and down regulation same?
qurl you have a deathwish
What force causes an object to change direction?
gravity (up to down) friction
What causes the moon to speed up or slow down in orbit?
time of the season
What causes liquid in thermometer to travel up and down in tube?
Heat causes Mercury in the thermometer to expand, where as when it is cooled, it contracts.
Does up-regulation involve the loss of receptors and prevents the target cells from overreacting to persistently high hormone levels?
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.
What is manual handling operations regulation 1992?
Manual handling operation regulations 1992 is an act which tell an employee how the pick up equipment how to put it down (straight back kneel down)
