Enzyme Activity

I should really study for my biology exam tomorrow. But the weather is crazy - hail, thunder and all - so my mind keeps wandering. On the bright side - I'm going to Germany tomorrow . . . I'm not sure if I'm gonna bring my computer yet - so maybe you won't hear from me before monday. But then I'll have a lotta stuff (for example outfit I'm gonna wear at my old school's prom on saturday)
