Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A researcher finds that an enzyme operates at an optimal temperature of 40°C and pH of 7.2. What would you predict will happen to the enzyme's effectiveness at a temperature of 60°C and a pH of 5.0?

💡 Hint: Consider what happens when enzymes are outside their optimal conditions.

Challenge 2 Hard

Design an experiment to measure the effect of substrate concentration on enzyme activity. Discuss the variables involved, controls, and expected outcomes.

💡 Hint: Think about the relationship between substrate concentration and enzyme activity.
