Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given an enzyme with Km of 1 mM and Vmax of 100 µM/s, calculate the initial reaction rate at a substrate concentration of 500 µM.

💡 Hint: Remember to convert units to be consistent.

Challenge 2 Hard

A reaction exhibits zero-order kinetics with a rate constant of 0.1 M/s. If the initial concentration is 2 M, how long until the concentration drops to 1 M?

💡 Hint: Focus on how time relates to concentration changes.
