I give you 100mL of a 3 M aqueous glucose stock solution. I need you to dilute it to make 100mL of a solution that is 0.03M. To accomplish this task, you have 2 additional 100 mL graduated cylinders and however much distilled water you need. The graduated cylinders are not really accurate at measuring any volume less than 5mL. (10 pts) How would you dilute 3M stock solution into 0.03 M solution? Explain strategy.

Suppose that you have isolated the enzyme sucrase (able to hydrolyze sucrose into glucose and fructose), and you wish to determine the nature of inhibitor A for this enzyme. You have prepared five different concentrations of substrate (sucrose), and five different concentrations of inhibitor A (plus the control, with zero mM of inhibitor A). The following Table lists the inhibitor A concentrations [I], substrate concentrations [S], and resulting enzyme velocities (Vo) for all six of these experiments: [I] [S] Vo...
