What end product from a metabolic pathway binds to an enzyme involved in a reaction at the beginning of the pathway. changing the shape of the active site and preventing the enzyme from?
The end product of a metabolic pathway can bind to the enzyme involved in the beginning of the pathway, acting as an inhibitor. This typically changes the shape of the enzyme's active site, preventing the enzyme from binding to its substrate and carrying out the reaction. This regulatory mechanism is known as feedback inhibition.
What is an excess of end-product molecule alters the shape of the first enzyme in the pathway and shuts off that metabolic pathway?
The phenomenon you are describing is known as "feedback inhibition." In this regulatory mechanism, an excess of the end-product molecule binds to an allosteric site on the first enzyme of the metabolic pathway, causing a conformational change that reduces the enzyme's activity. This effectively shuts off the pathway, preventing the overproduction of the end product and ensuring metabolic balance within the cell. Feedback inhibition is a crucial regulatory strategy in biochemical pathways.
Which method of enzyme control is when the products of a reaction inhibit the working of an enzyme by binding to the enzyme?
The method of enzyme control where the products of a reaction inhibit the enzyme by binding to it is known as feedback inhibition. In this process, the end product of a metabolic pathway binds to an enzyme involved in the pathway, reducing its activity and preventing the overproduction of the product. This regulatory mechanism helps maintain homeostasis and balance within the cell.
How can a molecule serve as both an inhibitor and substrate in an enzyme system characterized by feedback inhibition?
In a feedback inhibition system, a molecule can act as both an inhibitor and substrate by participating in the metabolic pathway it regulates. As a substrate, it is converted into a product by an enzyme, which then can accumulate and bind to an earlier enzyme in the pathway, inhibiting its activity. This dual role helps maintain homeostasis, ensuring that the pathway is active only when needed, preventing overproduction of the end product. This regulatory mechanism allows for fine-tuning of metabolic processes based on the cell's needs.
What is feedback inhibition?
A cellular control mechanism in which an enzyme that catalyzes the production of a particular substance in the cell is inhibited when that substance has accumulated to a certain level, thereby balancing the amount provided with the amount needed.

What is the slowing or stopping of an early reaction in a biochemical pathway when levels of the end product become high called?
The slowing or stopping of an early reaction in biochemical pathway when levels of the end product become high is to stimulate electron transport chain. Electron transport chain is a series of linked chemical reactions.
An excess of end-product molecules alters the shape of the first enzyme in the pathway and shuts off that metabolic pathway?
Feedback Inhibition
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.
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 is the shutting down of a biochemical pathway caused by a key enzymes sensitivity to the level of the pathways product?
This phenomenon is known as feedback inhibition, where the final product of a biochemical pathway binds to the enzyme responsible for an early step in the pathway, inhibiting its activity. This mechanism helps regulate the overall rate of the pathway, ensuring that the cell does not produce excessive amounts of the final product.
How is negative feedback control of multienzyme complexes turned off?
Negative feedback control of multienzyme complexes is turned off when the end product of a metabolic pathway no longer inhibits the initial enzyme in the pathway. This can occur through dilution of the product, a decrease in its concentration, or the binding of the product to a different site that does not inhibit the enzyme. Additionally, changes in cellular conditions, such as pH or the availability of substrates, can also lead to the release of inhibition, allowing the pathway to resume activity. Ultimately, the balance between product concentration and enzyme activity determines the efficacy of negative feedback control.
