Expert Answer:

 

CHARACTERISTICS OF ENZYMES:

  • Enzymes alter or speed up the rates of chemical reactions that occur in a cell.
  • Enzymes remain unchanged after the reaction.
  • They are affected by pH and temperature.
  • They may sometimes require co-enzymes for their action.
  • They catalyse reversible reactions.

FACTORS AFFECTING ENZYME ACTIVITY:

  • Temperature-
  • By increasing the temperature, the enzyme activity is increased from its inactive state.
  • The enzyme is most active at its optimum temperature.
  • At high temperatures, the enzymes are denatured and they lose their activity.
  • pH-
  • By increasing the pH, the enzyme activity is increased from its inactive state.
  • The enzyme is most active at its optimum pH.
  • At high pH, the enzymes are denatured and they lose their activity.
  • Some enzymes work best at neutral pH.
  • Some enzymes work best at acidic pH.
  • Some enzymes work best at basic pH.
