Identify an independent variable in the experiment shown in Figure 3. Justify using a temperature range of 5°C to 25°C when the scientists performed the experiments described. Based on Figure 2, describe the effect of adding AMP to the reactions carried out at 25°C. Based on Figure 2, calculate the fold increase in the reaction rate (how many times greater the reaction rate is) at 25°C in the presence of 0.5 mM AMP when the concentration of F6P increases from 0.2 mM to 0.9 mM.
