Title: What function does this secondary loop serve in addition to the primary one? Post by: rmanzano on Aug 17, 2013 There is a secondary negative feedback loop where thyroxin feeds back to the pituitary.
Title: What function does this secondary loop serve in addition to the primary one? Post by: irina on Aug 17, 2013 I think you're talking about Feed back inhibition. In this process, the end product inhibits the reactants or the catalyst when the end product level is high thus putting a stop to further production and waste of energy.
Eg: when there's sufficient amt of Thyroxin, thyroxine blocks the activity of pituitary as pituitary secretes a hormone that stimulates the thyroid gland to produce thyroxine. |
