Work in partners (one person is toothpickase, other person is data recorder). Get 40 toothpicks to start the activity. Finally, note the two ground rules below: Rule #1: The toothpick breaker cannot look at the pile of toothpicks … after all, enzymes do not have eyes to search for their substrate molecules either! Look away or close your eyes. Rule #2: The toothpick breaker does NOT break already broken toothpicks. Those are product molecules NOT the substrate the enzyme works with. Also, you cannot create separate piles of product and substrate molecules float around randomly in solution and mix up naturally. Time of total enzyme activity (seconds) Total substrate molecules broken down 0 0 10 30 60 90 Y axis label & units: _________________ X axis label & units: ___________________________ Title: ____________________________________________ See back for final analysis

Finally, we can analyze how enzyme activity changed over time. Enzyme activity is a rate (# of substrate molecules hydrolyzed per second), which is represented by the slope of our curve on the graph. Slopes can be estimated by calculating: __ Δy __ = __y 2 y 1 __ Δx x 2 x 1 Use your data points on your graph to calculate the slopes for the following time intervals: Time intervals (seconds) # substrate molecules broken per second (or speed of enzyme activity) 0 10 10 30 30 60 60 90 Key questions: 1) What happened to the speed of enzyme activity throughout the course of the activity? 2) Explain why the enzyme speed changed.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
