Which Of The Following Claims Regarding Enzyme Feedback Inhibition Is Untrue?

Feedback inhibition is a crucial regulatory mechanism in cells that slows down or can even turn off biochemical pathways to help cells be efficient. It is accomplished by an end product acting as either a competitive inhibitor or an allosteric inhibitor of an enzyme. The statement “feedback inhibition is difficult to reverse” is false, as it requires the synthesis of new enzymes and is not a true statement.

False statements about feedback inhibition include the statement that it is difficult to reverse and requires the synthesis of new enzymes. Feedback inhibition is usually exerted through allosteric effects and is directed at the enzyme that catalyzes the first committed step in a metabolic pathway. However, the final product of a metabolic pathway is usually the compound that regulates the pathway.

In summary, feedback inhibition is an important regulatory mechanism in cells that down-regulates enzyme activity by the accumulation of a product earlier in the pathway. It is typically easily reversible and does not change the amount of enzyme. The statement “feedback inhibition is difficult to reverse” is false, as it affects the rate of reaction and does not change the concentration of the enzyme. Feedback inhibition is typically easily reversible and does not affect the amount of enzyme.

Which of the following statements is true about enzyme inhibition?

So, the correct answer is option B. Competitive inhibition occurs when the substrate and the inhibitor compete for active site on the enzyme.

Note: -The binding of the inhibitor with the enzyme is reversible and adding a large amount of substrate may not help to overcome the non- competitive inhibition.

Which of the following is not true about enzymes responses?

Answer and Explanation: Of the following regarding enzymes, enzymes being consumed by the reaction they catalyze is incorrect. Enzymes are special in that they’re able to catalyze many different reactions without being consumed or used up by the specific reaction.

Which statement about feedback inhibition of enzymes is not true?

The false statement concerning feedback inhibition and allosteric sites is 3. Enzyme allosteric sites are not used in feedback inhibition.

What is feedback inhibition of an enzyme?

Feedback inhibition is performed by allosteric regulation, which is the process where the function of the enzyme is affected by the binding of a molecule to the allosteric site. The allosteric site is the location of an enzyme where a molecule that is not a substrate binds and changes the shape of the enzyme.

Which of the following statements is false in relation to enzyme?

An enzyme allows the reaction to go through a more stable transition state than would normally be the case. An enzyme provides an alternate pathway having lower activation energy. The statement (C) is false with respect to an enzyme’s ability to catalyses a reaction.

Which of the following statements about enzymes is false?

Enzymes are destroyed by chemical processes is not true Catalysts like enzymes speed up chemical reactions without consuming or destroying anything in the process.

Which statement regarding enzymes function is false?

The false statement about enzyme function is that enzymes must be synthesized for each new chemical reaction. Enzymes are reusable and do not have to be synthesized each time they catalyze a reaction.

Which of the following statements about enzyme function is false?

Enzymes must be synthesized for each new chemical reaction. This statement is false because enzymes are not required to be synthesized for each new chemical reaction. Enzymes are proteins that can be reused and are not consumed during the reaction.

Which statement is not true about enzyme inhibition?

The statement that is NOT true about enzyme inhibition is: ‘ In noncompetitive inhibition, the inhibitor binds to the allosteric site of the substrate. ‘ So, the correct answer is b. In noncompetitive inhibition, the inhibitor binds to the allosteric site of the substrate.

Which statement about enzyme inhibitors is true?

The true statement about enzyme inhibitors is that the action of inhibitors can be reversible or irreversible. Competitive inhibitors bind to the enzyme’s active site, while noncompetitive inhibitors bind to a different site and change the enzyme’s shape and activity.

What statement is false about inhibitors?

Final answer: The false statement about a competitive inhibitor is that it irreversibly inhibits the enzyme. Competitive inhibitors reversibly bind at the active site, and their effects can be overcome by increasing substrate concentration.
