Question

Identify the correct statements regarding the enzymes
I) Almost all enzymes are proteins
II) Enzymes are not specific in nature
III) Enzymes work effectively in the pH range of 5–7
IV) Enzymes work effectively between 310 K and 330 K temperature

• A. I& II only
• B. II& III only
• C. I& III only
• D. II& IV only

Hint:

Enzymes are protein molecules that act as biological catalysts. They work best in a specific pH and temperature range, and are highly specific to the reactions they catalyze.

Answer 1

The Correct Option is C

Statement I: True — Enzymes are mostly globular proteins.
Statement II: False — Enzymes are highly specific in their action.
Statement III: True — Most enzymes function effectively in a narrow pH range of 5–7.
Statement IV: False — The effective temperature range is usually around 298–310 K; 330 K is often too high for many enzymes.
