Very hard

Enzymes that catalyse the splitting of bonds with the addition of water belong to the class called

Correct answer: A. hydrolases

  • A. hydrolases
  • B. ligases
  • C. transferases
  • D. isomerases

Explanation

Hydrolases, such as amylase, lipase and peptidase, break bonds by inserting water. Transferases move groups between molecules, ligases join molecules using ATP, and isomerases rearrange a molecule without changing its formula.

About Characteristics of Enzymes

Enzymes are globular biological catalysts that lower activation energy without being consumed, usually showing specificity for particular substrates. Questions cover active sites, enzyme substrate complexes, the lock and key and induced fit models, intracellular and extracellular action, and the effects of denaturation, while distinguishing enzymes from non biological catalysts.
