Question

Enzymes are the molecules which -

• A. Provides energy to the cell
• B. Catalyse biochemical reactions
• C. Saves the genetic information
• D. Transmits genetic information generation to generation

Hint:

Enzymes act as biological catalysts — they lower the activation energy and speed up biochemical reactions but are not consumed in the process.

Answer 1

The Correct Option is B

Step 1: Recall the role of enzymes.
Enzymes are biological catalysts, usually proteins (sometimes RNA molecules), that increase the rate of biochemical reactions in living organisms without being consumed.

Step 2: Analyze the options.
- (1) Provides energy to the cell → Wrong, ATP provides energy, not enzymes.
- (2) Catalyse biochemical reactions → Correct, this is the main function of enzymes.
- (3) Saves the genetic information → Wrong, DNA does this, not enzymes.
- (4) Transmits genetic information generation to generation → Wrong, this is done by DNA/RNA, not enzymes.

Step 3: Conclusion.
Thus, the correct answer is that enzymes catalyse biochemical reactions.

Final Answer: \[ \boxed{\text{Enzymes catalyse biochemical reactions.}} \]
