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 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.
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.
What is an example of an feedback inhibition?
an excess of a product of one reaction causes the enzyme of another reaction to stop working.
If an enzymatic reaction was controlled by feedback inhibition would it be expected to stop?
Yes, feedback inhibition is a mechanism where the end product of a reaction inhibits the enzyme earlier in the pathway. This helps regulate the production of the end product by preventing over-accumulation. So, the enzymatic reaction would slow down or stop when the end product reaches a certain concentration.
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.

How does 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 term describes a process the cell to control metabolism?
feedback inhibition
What describes a process the cell use to control metabolism?
feedback inhibition
What term a process the cell uses 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 !
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.
What are the types of feedback inhibition?
There are two main types of feedback inhibition: competitive inhibition, where an inhibitor competes with the substrate for the active site of an enzyme; and non-competitive inhibition, where an inhibitor binds to a site on the enzyme other than the active site, altering the enzyme's shape and reducing its activity.
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.
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.
