an excess of a product of one reaction causes the enzyme of another reaction to stop working.
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.
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.
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 glycolysis turned off?
When an enzyme in a pathway is inhibited by the product of the reaction sequence, feedback inhibition occurs. The product molecule "feeds back" to stop the reaction sequence when the product is abundant.
Which is an example of feedback inhiibition?
An example of feedback inhibition is the regulation of the enzyme aspartate transcarbamoylase (ATCase) in the synthesis of pyrimidines. When the end product, cytidine triphosphate (CTP), accumulates, it binds to ATCase, causing a conformational change that decreases the enzyme's activity. This prevents excessive production of CTP, thereby maintaining metabolic balance. This mechanism illustrates how cells self-regulate biochemical pathways to prevent overaccumulation of products.

A decrease in blood glucose that causes the inhibition of insulin is an example of?
A decrease in blood glucose that causes the inhibition of insulin secretion is an example of a negative feedback mechanism. In this case, low blood glucose levels trigger the inhibition of insulin release to prevent further lowering of blood sugar and maintain homeostasis.
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.
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.
What describes a process the cell use to control metabolism?

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 !
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
Positive feedback differs from negative feedback in that?
Most of the mechanisms in our body are regulated by negative feedback inhibition. In this type of process, the end product shuts off or reduces the intensity of the original stimulus. Production of certain hormones when mother is giving birth to a child is regulated by positive feedback inhibition. In this type of process, response leads to an even greater response.
