WHAT DO WE MEAN BY “OPTIMAL CONDITIONS”? Enzymes have to be able to function in different locations Very specific structure/function relationship Across a range of “conditions” (e.g., a broad range of temperatures, pH levels, or concentration), “optimal conditions” are the ones with the highest enzyme reaction rate What’s best changes depending on the enzyme and the organism K.

PROCEDURE (PG. 55) 1. Note which question you are assigned 2. As a group, formulate a hypothesis and discuss how you are going to set up an experiment to test the hypothesis. (Note which materials are available to you!) 3. Record the relative degree of activity you observe. You should have some organized way of recording data. 4. Each group member should record all details of your experiment, including your conclusion and any potential sources of error. 5. Send someone up to share your main results and conclusions on the board K. BARRETTO FOR BIOL101 | LAB ACTIVITIES FROM DOWDY & YONENAKA 2018

    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.
