sensor, intergrator and effector
Negative feedback is a feedback where it is used in negative side in a closed loop system.Such as a inverting side feedback in op-amp.
The ADH feedback loop is an example of a negative feedback loop. Negative feedback loops occur when the output of a system acts to oppose the changes to the input of the system. This is the case with ADH because when there is not enough water, the hypothalamus and pituitary gland work to release ADH so that the body can retain more water.
Negative Feedback: Enzyme A makes Substance A when Substance A is not available in the Diet. When Substance A becomes available in the Diet, Enzyme A is no longer required and The Negative Feedback loop shuts down the production of Enzyme A.
A: DEFINITELY NOT Open loop is defined as no feedback. any kind of negative feedback will reduce the gain
in negative feedback. when an enzyme (negative feed back mechanism) produces too much of a molecule or substance that substance binds to the enzymes allosteric site to hault production of that substance (negative feedback response). and the whole process is the negative feedback loop.
- temperature - negative feedback loop - positive feedback loop - water balance
The ADH feedback loop is an example of negative feedback. When blood osmolality is high, it triggers the release of ADH, which acts to reabsorb water in the kidneys, thereby reducing blood osmolality. Once blood osmolality decreases, ADH secretion diminishes, creating a feedback loop that maintains homeostasis.
A: It does not. The loop becomes unstable ONLY if there is positive feedback either voltage or phase. For a close loop to be stable negative feedback is required.

The sensor component of a negative feedback loop detects changing conditions and sends signals to the control center for regulating responses to maintain homeostasis.
A negative feedback loop works to counteract changes in a variable, promoting stability within a system. When an initial change occurs, the negative feedback mechanism detects this deviation and triggers responses that reduce or negate the change. For example, if a body temperature rises, mechanisms like sweating are activated to lower it back to the set point. Thus, the negative feedback loop effectively dampens the initial change, restoring equilibrium.
This is known as a feedback loop. When a system's output influences its input in a way that reduces the output, it can lead to the system shutting down or destabilizing. This feedback loop can have either positive (amplifying) or negative (stabilizing) effects on the system.
