Question

Which of the following statements are true?
(i) In case of microbial enzymatic reactions, elimination and decomposition of waste materials are avoided.
(ii) Microbial enzymes are active only at high temperature.
(iii) MIcrobial enzymes are eco-friendly.

• A. (i) and (ii)
• B. (i) and (iii)
• C. (ii) and (iii)
• D. (i), (ii) and (iii)

Answer 1

The correct option is B (i) and (iii)

Nowadays, instead of chemical catalysts, microbial enzymes are used. They are active at low temperature and pH. In case of microbial enzymatic reactions, elimination and decomposition of waste material are avoided and enzymes can be reused. Hence, such enzymes are eco-friendly.
