Control of body temperature
slideplayer.com
- An example of negative feedback is the control of body temperature. If the body gets too hot, it begins to sweat to try to reduce the temperature. If the body gets too cold, it begins to shiver to try to raise the temperature. The glucose concentration in the blood is also controlled by negative feedback mechanisms.

Jun 18, 2016 · Key points. Homeostasis is the tendency to resist change in order to maintain a stable, relatively constant internal environment. Homeostasis typically involves negative feedback loops that counteract changes of various properties from their target values, known as set points.
The ∆G of a reaction can be negative or positive, meaning that the reaction releases energy or consumes energy, respectively. A reaction with a negative ∆G that gives off energy is called an exergonic reaction.
Jul 30, 2017 · Negative feedback is a type of regulation in biological systems in which the end product of a process in turn reduces the stimulus of that same process. Feedback, in general, is a regulatory mechanism present in many biological reactions.
Negative feedback loops help maintain a normal range or balance within an organism. They reduce the initial effect of the stimulus. Receptors detect any deviations from the normal range (stimuli) which results in a corrective mechanism to return the factor back to its normal range.
Here, we’ll look at some types of energy that are particularly important in biological systems, including kinetic energy (the energy of motion), potential energy (energy due to position or structure), and chemical energy (the potential energy of chemical bonds).

The free energy of a system changes during energy transfers such as chemical reactions, and this change is referred to as ΔG or Gibbs free energy. The ΔG of a reaction can be negative or positive, depending on whether the reaction releases energy (exergonic) or requires energy input (endergonic).
Jul 8, 2020 · The amount of free energy is the same for both the forward and reverse reaction, but the energy is absorbed (positive) by the endergonic reaction and released (negative) by the exergonic reaction. For example, consider the synthesis and degradation of adenosine triphosphate (ATP).
