FRQ prompt
Free Response Question: A researcher studies the effect of temperature on enzyme activity. She tests the enzyme amylase at 10°C, 25°C, 37°C, 50°C, and 70°C and measures the rate of starch breakdown. (a) Predict the shape of the rate vs. temperature graph and explain why enzyme activity changes at temperatures above the optimal. (b) If the researcher adds a competitive inhibitor to the reaction mixture at 37°C, describe how the rate would change and explain the mechanism. (…Practice full FRQs
