How does feedback inhibition works?
Feedback inhibition works when the product of the process is an inhibitor of one or more steps in the process producing the product. An example is the release of insulin upon consumption of food. Eating releases raises blood sugar and high blood sugar releases insulin, which reduces blood sugar levels.
End products of biosynthetic pathways often act to block the initial step in that pathway This phenomenon is called?
metabolic inhibition
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
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.

metabolic inhibition
When a pathway is subject to allosteric feedback inhibition ...?
an accumulation of effectors slows the pathway.
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.
