An enzyme in potato cells causes oxygen to be produced from hydrogen peroxide.
Cubes of potato were incubated with hydrogen peroxide at different temperatures.
The numbers of bubbles of oxygen released per minute were counted at each temperature.
The table shows the results.
The results suggest the optimum temperature for the enzyme is between which two values?
${15^ \circ }C$ and ${35^ \circ }C$
2 )
${35^ \circ }C$ and ${45^ \circ }C$
3 )
${35^ \circ }C$ and ${55^ \circ }C$
4 )
${45^ \circ }C$ and ${55^ \circ }C$
