NEETChemistryBiomolecules
Given below are two statements regarding enzymes: Statement I: Almost all enzymes are globular proteins. Statement II: Enzymes increase the magnitude of activation energy to speed up biochemical reactions. In the light of the above statements, choose the most appropriate answer from the options given below:
Options
- ABoth Statement I and Statement II are correct
- BBoth Statement I and Statement II are incorrect
- CStatement I is incorrect but Statement II is correct
- DStatement I is correct but Statement II is incorrect
Correct answer
D. Statement I is correct but Statement II is incorrect
Step-by-step solution
Statement I is correct because chemically, almost all enzymes are globular proteins. Statement II is incorrect because enzymes act as biocatalysts by providing an alternate pathway with a lower activation energy. They reduce, rather than increase, the magnitude of activation energy required for a biochemical reaction to proceed. Answer: Statement I is correct but Statement II is incorrect
