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.
