Question

The activity of an enzyme becomes ineffective:

• A. at low temperature
• B. at atmospheric pressure
• C. at high temperature
• D. in aqueous medium.

Answer 1

The correct option is C at high temperature

• 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.
  
• Enzymes are highly active under optimum temperature.
  
• Enzymes are highly active under optimum pH.
• The activity of enzymes gets increased in presence of activators and co-enzymes.
