Enzymes — practice question

An enzyme in potato cells breaks down hydrogen peroxide to produce oxygen. Cubes of potato tissue were put into a hydrogen peroxide solution at different temperatures. At each temperature, the number of oxygen bubbles released per minute was recorded. The table shows the results. From the results, the optimum temperature for the enzyme appears to lie between which two values?

  • A$15\degree\text{C}$ and $35\degree\text{C}$
  • B$35\degree\text{C}$ and $45\degree\text{C}$
  • C$35\degree\text{C}$ and $55\degree\text{C}$
  • D$45\degree\text{C}$ and $55\degree\text{C}$
