What is feedback inhibition simple definition?

What is feedback inhibition simple definition?

feedback inhibition, in enzymology, suppression of the activity of an enzyme, participating in a sequence of reactions by which a substance is synthesized, by a product of that sequence. Feedback inhibition is a mechanism by which the concentration of certain cell constituents is limited.

What is feedback regulation of a metabolic pathway?

feedback regulation A process by which the product of a metabolic pathway influences its own production by controlling the amount and/or activity of one or more enzymes involved in the pathway.

Why is feedback inhibition a common process in metabolic pathways?

Feedback inhibition is important for the metabolic pathways because this process restricts the pathways from producing excessive amounts of products (nucleic acids, proteins, and other essentials) and by-products.

Which of the following is an example of feedback inhibition in a metabolic pathway?

An example of feedback inhibition is the inhibition of the activity of the enzyme hexokinase by glucose 6-phosphate in glycolysis. This enzyme catalyses conversion of glucose into glucose 6-phosphate but as the reaction proceeds, increase in concentration of glucose 6-phosphate inhibits the activity of hexokinase.

How does feedback inhibition in nitrogen metabolism work?

Feedback inhibition works by deactivating an enzyme using the product of the reaction the enzyme catalyzes. Enzymes bind to molecules with active sites that are specifically designed to fit with the molecule undergoing the reaction.

How does feedback inhibition affect regulation of metabolism?

Feedback inhibition is when a reaction product is used to regulate its own further production. Cells have evolved to use feedback inhibition to regulate enzyme activity in metabolism, by using the products of the enzymatic reactions to inhibit further enzyme activity.

What is the purpose of feedback inhibition quizlet?

Feedback inhibition allows cells to control the amounts of metabolic products produced. If there is too much of a particular product relative to what the cell’s needs, feedback inhibition effectively causes the cell to decrease production of that particular product.

What is feedback inhibition explain the function importance of feedback inhibition in glycolysis?

Feedback inhibition is also necessary to prevent enzymes from breaking down too many molecules that are energy sources for the cell, such as glucose. Inhibition takes place in glycolysis, the process of breaking down the sugar glucose to produce the cell’s “energy currency” molecule ATP.

How does feedback inhibition regulate metabolic pathways quizlet?

How does feedback inhibition regulate metabolic pathways? Metabolic pathways are regulated by controlling enzyme activity. The binding of an activator to a regulatory site keeps the shape that has functional active sites while the binding of an inhibitor keeps the inactive form.

Which is a good example of how feedback inhibition is used to regulate metabolic pathways in cells quizlet?

The production of both amino acids and nucleotides is controlled through feedback inhibition. For an example of feedback inhibition, consider ATP. It is the product of the catabolic metabolism of sugar (cellular respiration), but it also acts as an allosteric regulator for the same enzymes that produced it.

How does feedback inhibition work?

Feedback inhibition, in enzymology, suppression of the activity of an enzyme, participating in a sequence of reactions by which a substance is synthesized, by a product of that sequence. When the product accumulates in a cell beyond an optimal amount, its production is decreased by inhibition of an enzyme involved in its synthesis.

What is feedback inhibition Quizlet?

What is the purpose of feedback inhibition quizlet? Feedback inhibition allows cells to control the amounts of metabolic products produced. If there is too much of a particular product relative to what the cell’s needs, feedback inhibition effectively causes the cell to decrease production of that particular product.

What is feedback inhibition in microbiology?

In biology, feedback inhibition refers to the mechanisms that control certain processes and functions within cells, the body and even the environment. At its most basic, feedback inhibition means that when some sensor gets a certain amount of feedback from the environment, it turns another system on or off.

What is enzyme feedback inhibition?

Feedback inhibition is also necessary to prevent enzymes from breaking down too many molecules that are energy sources for the cell, such as glucose. Inhibition takes place in glycolysis , the process of breaking down the sugar glucose to produce the cell’s “energy currency” molecule ATP .
