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 function as biological catalysts, primarily proteins (or sometimes RNA), accelerating biochemical reactions within living organisms without undergoing consumption.

Step 2: Analyze the options.
- (1) Provides energy to the cell → Incorrect. ATP supplies energy; enzymes do not.
- (2) Catalyse biochemical reactions → Correct. This is the primary function of enzymes.
- (3) Saves the genetic information → Incorrect. DNA stores genetic information; enzymes do not.
- (4) Transmits genetic information generation to generation → Incorrect. DNA/RNA handles the transmission of genetic information; enzymes do not.

Step 3: Conclusion.
Therefore, the accurate description is that enzymes catalyse biochemical reactions.

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