Question

Which of the following is not correct for enzyme catalysis ?

• A. The enzyme activity is maximum at optimum pH which is between 5-7.
• B. Each enzyme is specific for a given reactions.
• C. The favourable temperature range of enzyme activity is between 50 – 60 ${ } ^ { \circ } \mathrm { C }$.
• D. The enzymatic activity is increased in presence of certain substances called co – enzymes.

Answer 1

Answer: (C)

The favourable temperature range of enzyme activity is between 50 – 60 ${ } ^ { \circ } \mathrm { C }$.

Answer 2

The enzymatic activity is destroyed at about $70 ^ { \circ } \mathrm { C }$ . The favourable temperature range for enzymatic activity is $25 - 37 ^ { \circ } \mathrm { C }$ .
