An enzyme near the beginning of a metabolic pathway is allosterically inhibited by the end product of the pathway.
So the feedback inhibition realizes that once we get to a certin level of something made in the cell, it will become an allosteric enzyme and block production so nothing is overproduced in the cell.

∙ 12y agoconserves energy and maintains homeostasis. in the case of cellular respiration, it does so by inhibiting the production of ATP; oxygen is the final electron acceptor on the etc and inhibits electron transfer which ultimately impacts ATP production so that excess is not produced.

and the biological pathway is like "oh, okay man, sorry"

What is the general features of allosteric regulation using the feedback inhibition?
enzymes situated at key steps in metabolic pathways are modulated by allosteric effectors these effectors are usually produced elsewhere in the pathway effectors may be feed-forward activators or feedback inhibitors kinetics are sigmoid ("S-shaped")
End products of biosynthetic pathways often act to block the initial step in that pathway This phenomenon is called?
metabolic inhibition
What happens when a protein is inhibited?
When a enzyme is inhibited (many proteins are enzymes), it just means that the enzyme will be reduced in its ability to catalyze a reaction. There are a few types of Inhibition like Competitive Inhibition, Noncompetitive Inhibition, and Irreversible Inhibition.
Regulatory device in which the product of a pathway binds to an enzyme early in the pathway?
feedback inhibition
The body mechanism in which the product or result of a process stops or limits the process?
Feedback inhibition
What term describes a process the cell uses to control metabolism?
by controlling the kinds of enzymes presentt in a cell, their concentration, and their activity
Inhibition of cellular enzymes could potnetially lead to?
inhibition of cellular enzymes could potentially lead to?
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.
Bacterial production of the enzymes needed for the synthesis of the amino acid tryptophan declines with increasing levels of tryptophan and increases as tryptophan levels decline This is an example o?
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
An enzyme citrate synthase in the Krebs cycle is inhibited by ATP What type of inhibition would this be?
Citrate synthase is inhibited by ATP. Obviously, the Krebs cycle produces ATP. This is the first step and one of the major regulatory steps in the pathway. If the cell has plenty of ATP, then it wouldn't need to keep making it, thus the pathway needs to be shut off. ATP inhibits the enzyme to shut off the pathway. This is an example of feedback inhibition (you can also call it negative inhibition or even product inhibition). Feedback inhibition is when the products of a certain biochemical pathway inhibit earlier enzymes, shutting down the pathway.

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.
