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.
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.
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.
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.

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 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 the allosteric enzyme curve illustrate the relationship between enzyme activity and the binding of regulatory molecules?
The allosteric enzyme curve shows how enzyme activity changes when regulatory molecules bind to the enzyme. This curve demonstrates that the binding of regulatory molecules can either increase or decrease enzyme activity, depending on the specific enzyme and regulatory molecule involved.
What is the Difference between enzyme and regulatory enzyme?
An enzyme is one kind of protein that can catalyze a specific reaction whereas a regulatory enzyme is the enzyme which can regulate a series of reaction which undergo in the living organism. So we can say every enzyme is not a regulatory one but the regulatory enzymes are obviously a special kind of enzyme.
Which kind of metabolic poison would most directly interfere with glycolysis?
The type of metabolic poison that would most directly interfere with glycolysis would be an agent that isn't metabolized, yet closely mimics the structure of glucose. Glycolysis acts as a metabolic pathway.
