The thing you alter. 1 of 9 What is the dependent variable? The thing that you measure. 2 of 9 What is equilibration? Placing enzyme and substrate separately in a water bath so that they reach the required temperature before the investigation begins. 3 of 9 How can temperature be kept constant? Carry out experiment in a water bath with a thermostat. 4 of 9 How can enzyme concentration be kept constant? If using an enzyme in living tissue, accurately measure mass. 5 of 9 How can substrate concentration be kept constant? Use accurately measured volume or mass of substrate. 6 of 9 How can pH be kept constant? Use pH buffers. 7 of 9 What are the two ways to measure reaction rate? Measure the amount of product made after a fixed period of time. Measure how much substrate has been used up after a fixed period of time. 8 of 9 What is the equation for reaction rate? Reaction rate= 1/time 9 of 9
