Factors that affect enzyme action — practice question

An investigation was carried out to examine how temperature affects the activity of the enzyme β-glucosidase. The enzyme was examined both in solution (free) and after being immobilised in alginate beads. The results are presented in the graph below. Which statement about the effect of immobilisation of β-glucosidase is correct?

  • AIt increases the kinetic energy of the enzyme.
  • BIt inhibits the activity of the enzyme.
  • CIt reduces the optimum temperature of the enzyme.
  • DIt stabilises the enzyme against denaturation.
