an excess of a product of one reaction causes the enzyme of another reaction to stop working.

∙ 13y agoIt is a simple and energy efficient way to regulate the production of substances in the cell where enzymes in a metabolic pathway are inhibited by their downstream products.
This slow's the flux through a metabolic pathway and maintains homoeostasis preventing a build up of the product which if left unchecked could build up to toxic levels as the enzyme would continue to create the substance as long as enough reagents were present regardless of the damage it could cause to the cell or the organism.for example, if a cell is working very hard and its ATP production begins to decrease, aeroobic respiration increases.when ATP is sufficent o meet demand, aerobic respiration slows, sparing valuable organic molecules for other necessary funtions.

Do you think that feeling of fullness and hunger are examples of feedback inhibition?
The feeling of fullness and hunger are examples of the negative feedback inhibition.
The process by which the product of a system shuts down the system or limits its operation is called the inhibition?
feedback inhibition
Why is ACTH elevated in Addisons disease?
The steroid hormones produced by the adrenal cortex exhibit feedback inhibition on ACTH production, therefore a low concentration of corticosteroids (as seen in Addisons disease) will not exhibit this feedback inhibition. Without this inhibition, ACTH levels are not regulated and therefore rise.
Compare and contrast negative and positive feedback mechanisms and give some examples?
positive feedback mechanisms
In what sense does the pituitary take orders from the target organs under its command?
negative feedback inhibition
Do you think that feeling of fullness and hunger are examples of feedback inhibition?
The feeling of fullness and hunger are examples of the negative feedback inhibition.
The process by which the product of a system shuts down the system or limits its operation is called the inhibition?
feedback inhibition

End products of biosynthetic pathways often act to block the initial step in that pathway This phenomenon is called?
metabolic inhibition
When a pathway is subject to allosteric feedback inhibition ...?
an accumulation of effectors slows the pathway.
What are some examples for positive feedback?
This is an excellent question.
How do target organs most often regulate the pituitary gland?
Negative feedback inhibition
The body mechanism in which the product or result of a process stops or limits the process?
Feedback inhibition
Regulatory device in which the product of a pathway binds to an enzyme early in the pathway?
feedback inhibition
