Y U NO RISE?

5. Effects of Variables on Enzyme Reactions
Substrate Concentration:
How does enzyme activity change as substrate concentration increases? Explain your observations by discussing this reaction on a molecular level. Enzyme handout
Temperature:
How does temperature affect the activity of catalase? Explain your observations by discussing the effect of temperature on protein structure and molecular movement. Discuss both high and low temperature effects. Sections 3.13 and 5.15
pH:
How does pH affect the activity of catalase? Consider both high and low pH, and explain your observations by discussing the effect of pH on protein structure. Sections 3.13 and 5.15
