Question 17

A scientist investigates the rate of sucrose hydrolysis by the enzyme sucrase. The reaction mixture is kept at a constant temperature, and the concentration of reducing sugars produced is measured every 4 minutes. The table below shows the results of this investigation:

Time (minutes)Concentration of reducing sugars (mmol dm−3\text{mmol dm}^{-3}mmol dm−3)
00.0
418.4
829.2
1234.0

Calculate the difference between the rate of reducing sugar production in the first four minutes and the rate in the final four minutes.
