Negative feedback occurs when the output of a system reacts to cancel out the effects of an input of a system, as opposed to positive feedback (in which the actions/output is intensified or increased). The more negative, the more stable. Thus, with things being canceled out, the body maintains homeostasis.

An example of negative feedback in action is the maintenance of blood glucose levels and body temperature. With input of sugar, insulin is released to stabilize the body (on the other hand, without insulin, Diabetes can be diagnosed). With a raise in body temperature, blood vessels and pores are opened to release heat.

What is homeostatic regulation?

Homeostatic regulation is controlled in the body by the autonomic nervous system and seeks to maintain relatively stable conditions in the internal environment. The main gland of homeostasis is the hypothalamus and the major organ of homeostasis are the kidneys.


What mechanisms are involved in homeostatic mechanisms?

homeostatic mechanisms involve: - the regulation of blood glucose - breathing rate - heart rate - oxygen levels - osmoregulation (water levels) - thermoregulation (temperature control)


Homeostatic mechanisms are said to act by negative feedback because changes away from the normal state?

are detected and trigger responses that counteract those changes, bringing the system back towards the normal state. This creates a feedback loop that helps maintain stability and equilibrium within the body.


Are positive feedback and negative feedback both components of homeostasis?

Yes, both positive and negative feedback are components of homeostasis. Negative feedback helps to maintain a stable internal environment by reversing any deviations from a set point, while positive feedback amplifies the response to a stimulus, often to achieve a specific outcome in the body. Both types of feedback work together to regulate physiological processes and maintain balance within the body.


Parathyroid glands is a negative or positive feed back?

The parathyroid glands are involved in negative feedback regulation of blood calcium levels. When blood calcium levels are low, the parathyroid glands release parathyroid hormone (PTH) to increase calcium levels by stimulating calcium release from bones, absorption from the intestines, and reabsorption from the kidneys. Once calcium levels are restored, the release of PTH is inhibited, demonstrating negative feedback control.

What is the Primary mechanism of homeostatic regulation?

The body's primary mechanism of homeostatic regulation is negative feedback. This mechanism recognizes the problem, identifies the correction, and changes the variable.

What are two examples of homeostatic variables controlled by negative feedback?

Two examples of homeostatic variables controlled by negative feedback are body temperature regulation and blood glucose levels. In both cases, the body responds to deviations from the set point by initiating processes that work to bring the variable back within the normal range.


Why is negative feedback valuable in metabolic processes?

Negative feedback loops primarily focus on maintaining the body's homeostatic functions.


What is the effect of a negative feedback mechanism?

A negative feedback system is what occurs most commonly in your body systems. These keep everything in a homeostatic state.


Definition of negative feedback and positive feedback?

A: Any feedback that contributes to the input is positive feedback any feedback that subtract from the input is negative feedback


What are four conditions in the cell that must be kept in the homeostatic balance?

- temperature - negative feedback loop - positive feedback loop - water balance

Mechanism that allows the body to change an internal condition back to normal?

Homeostatic mechanisms return the body to its normal state. Most of these are controlled by negative feedback.

Does the enzyme that undergo negative feedback have any other function than to be regulated by its product?

Yes, enzymes that undergo negative feedback regulation typically have other important functions in the cell or organism. These enzymes are often involved in key metabolic pathways and play critical roles in maintaining cellular homeostasis and carrying out essential biological processes. The negative feedback regulation helps control the rate of these enzymatic reactions to ensure optimal function.
