Challenge Problems
Push your limits with advanced challenges
Calculate the time it would take for a membrane protein to diffuse laterally across a 10 μm cell within a given lateral diffusion rate.
💡 Hint: Think about diffusion as a random walk in two dimensions.
Discuss how increased temperature affects the fluidity of membranes regarding phase transitions and the impact on protein functions.
💡 Hint: Consider how we adjust refrigeration settings for food safety; too high can spoil!
