The regulation of blood is an example of a negative feedback loop. When blood pH gets either too high or too low, the body works to bring it back to normal

Sweating is part of the thermoregulation negative feedback loop. An increase in temperature triggers vasodilation and sweating, which is then stopped by a decrease in temperature and a return to baseline levels.

Enzyme inhibition negative feedback mai ay ga.
As product of enzyme increases it blocks the active site of enzyme. Like thereonine and aspartame

@@irtisamsbiology Sir Ap ka Lecture Acha tha Per Ap Ne yee nahee bataya kee product feedback me enzyme ke 2nd binding site people attached hota hai aur Substrate se Competition nahee kartaa?

[@drabdulrehmansir]

You means that in negative feedback there is non competitive inhibitions?

[@drabdulrehmansir]

Is it correct or not?

[@khanali1102]

@@drabdulrehmansir Yeah KPK books line se Maloom hotaa hai ke feedback inhibition is non competitive inhibition.

Legends got you

[@meharsuleman]

Assalam o alaikum ! The possible answer may be:
(1) ..corticosteroids increases = ACTH decrease
(2) insuline increase = cortisol decrease ( glucose)
(3) PIH incresae = prolactine decrease ...

[@HammadAhmad-n5r]
