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 reaction.
• C. The favourable temperature range of enzyme activity is between 50-60${}^{\circ }$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${}^{\circ }$C.

• Enzymes are macromolecular biological catalysts. Enzymes accelerate chemical reactions. The molecules upon which enzymes may act are called substrates and the enzyme converts the substrates into different molecules known as products.

Enzyme catalysis is unique in its efficiency and high degree of specificity.

• Enzymes are Highly specific nature.This says that enzyme is specific for a given reaction.
  
• Enzymes are highly active under optimum temperature.The optimum temperature range for enzymatic activity is 298-310K.
• Enzymes are highly active under optimum pH.Optimum pH level is between 5-7.
• The activity of enzymes gets increased in presence of activators and co-enzymes.
