Assertion: Cyanide causes death in animals by blocking cytochrome oxidase, a mitochondrial enzyme required for cellular respiration.
Reason: This is an illustration of non-competitive inhibition.
Both Assertion & Reason are True & the Reason is a correct explanation of the Assertion.
Both Assertion & Reason are True but Reason is not a correct explanation of the Assertion.
Assertion is True but the Reason is False.
Both Assertion & Reason are false.
Answers (1)
The Assertion is true, as cyanide does cause death in animals by blocking cytochrome oxidase, an essential mitochondrial enzyme necessary for cellular respiration.
However, the Reason is not a correct explanation of the Assertion. The inhibition of cytochrome oxidase by cyanide is actually an example of non-competitive inhibition, not competitive inhibition as stated in the Reason. In non-competitive inhibition, the inhibitor binds to a site on the enzyme other than the active site, altering the enzyme's structure and function.
Therefore, while both the Assertion and Reason are true, the Reason does not provide an accurate explanation for the Assertion.
Hence, the correct answer is option 2.
