Positive feedback is a process in which the end products of an action cause more of that action to occur in a feedback loop. This amplifies the original action. It is contrasted with negative feedback, which is when the end results of an action inhibit that action from continuing to occur. These mechanisms are found in many biological systems.

Sourced from Biology Corner The control of blood sugar (glucose) by insulin is a good example of a negative feedback mechanism. When blood sugar rises, receptors in the body sense a change. In turn, the control center (pancreas) secretes insulin into the blood effectively lowering blood sugar levels. Written by established researchers in both control engineering and systems biology, Feedback Control in Systems Biology explains how feedback control concepts can be applied to systems biology.

Like engineering systems, biological systems must also operate effectively in the presence of internal and external uncertainty—such as genetic mutations or temperature changes, for example. It is not surprising, then, that evolution has resulted in the widespread use of feedback, and research in systems biology over the past decade has shown that feedback control systems are widely found in Explore homeostasis with the Amoeba Sisters and learn how homeostasis relates to feedback in the human body. This video gives examples of negative feedback ( Biological systems utilize free energy and molecular building blocks to grow, to reproduce and to maintain dynamic homeostasis. Enduring Understanding 2.C Organisms use feedback mechanisms to regulate growth and reproduction, and to maintain dynamic homeostasis.

Jan 21, 2021 In living systems, feedback mechanisms or feedback loops works to bring the body towards homeostasis by either amplifying a specific biological 

The negative feedback process is sometimes compared to a house heating system, where temperatures above a certain level are detected by a thermostat. Negative feedback loops might occur in nature like in the case of carbon cycle where the cycle is balanced according to the concentration of carbon emission. 2.

The explanation lies with positive and negative feedback - powerful forces that shape the behaviour of all biological systems from cells to social systems and
