Question #115285

Difficulty: 8/10 | 🟢 Free

The Question

Given below are two statements regarding cellular metabolism and enzyme inhibition:

Statement I: Statins act as blood cholesterol-lowering agents by competitively inhibiting the enzyme responsible for cholesterol synthesis, thereby effectively lowering the activation energy of this metabolic pathway. Statement II: The competitive inhibition of a specific biomolecular synthesis pathway does not negate metabolism as a defining property of life, because metabolism represents the sum total of all chemical reactions occurring in the organism.

Choose the correct answer from the options given below:

Options

A.
Both Statement I and Statement II are correct
B.
Both Statement I and Statement II are incorrect
C.
Statement I is correct but Statement II is incorrect
D.
Statement I is incorrect but Statement II is correct

Common Mistakes

Conceptual Pivot: The trap lies in Statement I, where a well-known true fact ('Statins are competitive inhibitors') is seamlessly blended with a fundamentally flawed mechanism ('lowering activation energy').

Students often gloss over the second half of a statement if the first half matches their rote memory.

It also tests the conceptual understanding that 'Metabolism' is a macroscopic, emergent property (the sum total) rather than the uninterrupted flow of every single microscopic pathway.
