What is a feedback inhibition quizlet?

feedback inhibition. A method of metabolic control in which the end product of a metabolic pathway acts as an inhibitor of an enzyme within that pathway. competitive inhibition.

Which of the following would be an example of feedback inhibition?

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 work 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 meant by negative feedback inhibition quizlet?

Negative Feedback (Feedback Inhibition) Also called negative feedback; one of the products downstream in a reaction series comes back and inhibits the enzymatic activity of an earlier reaction.

Which is an example of example of feedback inhibition?

In feedback inhibition, the level of a variable is monitored, and a change in the positive direction triggers a response that counteracts the change. A simple example of feedback inhibition is a thermostat connected to a heater.

What is the advantage of feedback inhibition?

Feedback inhibition controls the production of amino acids. The benefits of feedback inhibition are that the building blocks such as 3-phosphoglycerate, which is crucial to other processes such as the Calvin cycle and glycolysis , are used optimally and without waste.

How does feedback inhibition 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 enzymes?

Feedback inhibition occurs when the end product of a reaction interferes with the enzyme that helped produce it. The inhibitor does this by binding to a second active binding site that’s different from the one attached to the initial reactant. The enzyme then changes its shape and can’t catalyze the reaction anymore.
