What does feedback inhibition involve?
Feedback inhibition involves the use of a reaction product to regulate its own further production (Figure 11). The cell responds to an abundance of the products by slowing down production during anabolic or catabolic reactions.
Which is a typical examples 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.
What does the term feedback inhibition describe quizlet?
feedback inhibition. effect of a product of a reaction sequence to decrease its further production by inhibiting the activity of the first enzyme in the pathway that produces it. induced fit.
Which of the following most accurately describes feedback inhibition?
Which of the following most accurately describes feedback inhibition? The end product of a metabolic pathway inhibits an earlier enzyme in the pathway.
How does feedback inhibition help the body maintain homeostasis?
Maintaining a stable and internal environment. How is feedback inhibition important in maintaining homeostasis? Feedback inhibition gives you responses telling your body that it is not at homeostasis. Process which stimulus produces a response that opposes original stimulus.
How does feedback inhibition allow a cell to manage its resources?
What is feedback inhibition? How does it allow a cell to manage its resources? It happens when a metabolic pathway is turned off by the inhibitory binding of its end product to an enzyme that acts early in the pathway.
Which of the following is an example of feedback inhibition quizlet?
Inhibition of anabolic enzymes by ATP is an example of feedback inhibition.
What molecule acts as an inhibitor in feedback inhibition?
For example, the energy carrier molecule ATP is an allosteric inhibitor of some of the enzymes involved in cellular respiration, a process that makes ATP to power cellular reactions. When there is lots of ATP, this feedback inhibition keeps more ATP from being made. This is useful because ATP is an unstable molecule.
What is feedback inhibition in glycolysis?
Feedback inhibition is the inhibition of an enzyme by a reaction product. As more glucose-6-phosphate is produced, the reaction rate slows down. Hexokinase governs the rate-limiting step of glycolysis in the brain and in red blood cells. In most cells, glycolysis is regulated during reaction 3.
What is feedback inhibition and how does it work?
Feedback inhibition and feedback repression are two types of enzyme inhibition mechanisms.
Which is a typical 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 are some examples of feedback inhibition?
Review of Enzymes. Ever made a cup from clay?
What are the two types of feedback inhibition?
Reversible Inhibition. The inhibitor binds to an enzyme via non-covalent transient bonds.
