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 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.
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.
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.
The shutting down of a biochemical pathway caused by a key enzyme's sensitivity to the level of the pathway's product?
Feedback Inhibition
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.
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 !
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.

Where could you find the inhibition mechanisms in E. coli of these amino acids L-valine L-isoleucine L-leucine L-lysine L-threonine L-phenolalanine and selenium-methionine?
In E. coli, the inhibition mechanisms of amino acid biosynthesis involve feedback inhibition. For L-valine, L-isoleucine, and L-leucine biosynthesis, an intermediate product (e.g., alpha-keto acid) typically acts as an inhibitor. L-lysine biosynthesis is inhibited by lysine itself, while threonine biosynthesis is feedback inhibited by isoleucine. Phenylalanine biosynthesis can be inhibited by accumulating levels of phenylalanine. Selenium-methionine incorporation can also be regulated through feedback inhibition mechanisms.
