Question

Why do enzymes function only under mild conditions?$(16.4,16.5)$

Short answer

• The enzymecan only function under mild conditions.

Step-by-step solution

Introduction Enzymes need temperature to function

1. Generally, catalysts require high temperature and high pressure.
2. Enzymes are biological catalysts that work only under physiological conditions: $\mathrm{pH}7.4$ and $37°\mathrm{C}$.
3. Enzymes catalyze biological activity bylowering the activation energy.

ExplanationThe enzyme can only function  under mild conditions. 

1. Most enzymes are globular proteins.
2. At high temperatures, the tertiary structure is distorted and inoperable.
3. At pH above or below the optimum pH, the structure of the enzyme changes and the active site is destroyed.
4. Therefore, the enzyme can only function under mild conditions.
