Bio173 Quiz 1 Name: _____________________________ GSI: ___________________ 1. The graph below represents the results of an experiment like the one you performed in Part III of the enzyme lab (diluting substrate to see the effect on rate of enzyme action). Dilution of Substrate 0 0.02 0.04 0.06 0.08 0.1 0.12 0 1/4 1/2 3/4 1 dilution rate (AU/min) 6 mM [catechol] 24 mM [catechol] a. Explain the difference between the two curves above. Be sure to cover the difference in shape and value, as well as describe what’s happening to the enzyme. (three points) b. The data points for the 24 mM curve above were derived from a different graph. Sketch that graph. (two points- one for proper axes, one for right shape of curve(s))
