NEETBotanyBiomolecules (B)
Read the following Assertion and Reason and choose the correct option. Assertion: When the reaction ultimately reaches a maximum velocity, it does not exceed by any further rise in concentration of the substrate Reason: The enzyme molecules are fewer than the substrate molecules and after saturation of these molecules, there are no free enzyme molecules to bind with the additional substrate molecules.
Options
- ABoth Assertion and Reason are true and Reason is correct explanation of Assertion
- BBoth Assertion and Reason are true but the Reason is not the correct explanation of Assertion
- CAssertion is true but the Reason is false
- DBoth Assertion and Reason are false
Correct answer
A. Both Assertion and Reason are true and Reason is correct explanation of Assertion
Step-by-step solution
The reaction ultimately reaches a maximum velocity which is not exceeded by any further rise in concentration of the substrate. This is because the enzyme molecules are fewer than the substrate molecules and after saturation of these molecules, there are no free enzyme molecules to bind with the additional substrate molecules
