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.
What else can I help you with?
End products of biosynthetic pathways often act to block the initial step in that pathway This phenomenon is called?
feedback inhibition. Feedback inhibition is a regulatory mechanism where the end product of a biosynthetic pathway inhibits the activity of the enzyme catalyzing the initial step, thereby regulating the overall rate of the pathway.
Why does feedback inhibition occur at the beginning of a metabolic pathway instead of in the middle?
Feedback inhibition at the beginning of a metabolic pathway allows for rapid control of the pathway by regulating the initial enzyme activity, helping to prevent unnecessary accumulation of intermediates. This control mechanism is more efficient and direct compared to inhibiting enzymes in the middle of the pathway, which may lead to wasteful buildup of metabolites before regulation occurs.
What other means does a cell use to control enzymatic activity?
Cells can control enzymatic activity through post-translational modifications such as phosphorylation, allosteric regulation, and feedback inhibition. They can also regulate enzyme synthesis and degradation, as well as by compartmentalizing enzymes in specific organelles or cellular locations.
Regulatory device in which the product of a pathway binds to an enzyme early in the pathway?
Feedback inhibition is the regulatory device in which the product of a pathway binds to an enzyme early in the pathway, inhibiting its own production. This mechanism helps prevent the over-accumulation of a particular product in the cell.
How is biofeedback related to enzyme activity?
Biofeedback is a technique that helps individuals control physiological processes through monitoring and feedback. Enzyme activity refers to the ability of enzymes to catalyze chemical reactions in living organisms. While biofeedback does not directly affect enzyme activity, it can help manage stress and improve overall health, which can indirectly impact enzyme function by creating a more favorable physiological environment for enzymatic reactions.
Inhibition of cellular enzymes could potnetially lead to?
inhibition of cellular enzymes could potentially lead to?
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?

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.
What term describes a process the cell to control metabolism?
feedback inhibition
What describes a process the cell use to control metabolism?
feedback inhibition

Do you think that feeling of fullness and hunger are examples of feedback inhibition?
Yes, the feeling of fullness and hunger are examples of feedback inhibition. When the body has enough nutrients, signals are sent to the brain to stop eating (fullness), and conversely, when nutrients are low, signals are sent to eat (hunger). This feedback mechanism helps regulate food intake and maintain energy balance in the body.
When a pathway is subject to allosteric feedback inhibition ...?
an accumulation of effectors slows the pathway.
What are the two types of Feedback Inhibition?
In my understanding there are three types of feedback inhibition:SIMPLE: Enzyme inhibited by single end product.CUMULATIVE: More than one end product inhibits the same enzyme. That means that each product exerts partial inhibition and inhibition is cumulative.CONCERTED: More than one end product must bind the same enzyme simultaneously for any inhibition.I !
