Identify the correct statement regarding enzymes :[AIEEE-2004]a)Enzyme...
Explanation:
Normal optimum temperature of enzymes is between 25degreeC to 40degreeC. Hence Enzymes are normally homogeneous catalysts that can be poisoned.Enzymes have well defined active sites and their actions are specific in nature.
so option D is correct.

Identify the correct statement regarding enzymes :[AIEEE-2004]a)Enzyme...
Understanding Enzymes
Enzymes are biological catalysts that facilitate and accelerate chemical reactions in living organisms. They are essential for various metabolic processes.
Why Option D is Correct
- Specificity: Enzymes are highly specific to the substrates they act upon. This specificity is due to the unique shape and chemical properties of their active sites.
- Active Sites: The active site of an enzyme is a well-defined region where substrate molecules bind. The structure of the active site allows only specific substrates to fit, much like a key fits into a lock.
- Mechanism of Action: Once the substrate binds to the active site, the enzyme undergoes a conformational change, facilitating the conversion of substrates into products. This process is often described by the "induced fit" model.
Why Other Options are Incorrect
- Option A: Enzymes typically function at physiological temperatures (around 37°C for humans) and are denatured at very high temperatures (T~1000 K is impractical for biological systems).
- Option B: Enzymes are generally homogeneous catalysts within a biological context, meaning they exist in the same phase as their substrates, and their specificity is critical for their function.
- Option C: While enzymes are designed to be robust, they can be inhibited or "poisoned" by certain molecules (inhibitors), which can bind to the active site or another part of the enzyme, preventing it from catalyzing reactions.
Conclusion
In summary, option D accurately describes enzymes as specific biological catalysts with well-defined active sites, essential for their function in biochemical reactions.
