I'm doing the effect of surface area on rate of rate using immobilised enzymes. I'm struggling with writing the research and rationale section.
I think I need to write about collision theory to explain why the surface area increasing would speed up the reaction? But everything I find on collision theory is about changing the surface area of the reactant rather than the enzyme?

Any help would be great
Thanks

If you are changing the size of the bead, you are increasing the surface area of the bead, not the enzyme itself. You cannot increase an enzymes surface area since it is a fixed structure, with a specific active site. By increasing the surface area of the bead, what you are actually doing is increasing the number of immobilised enzymes.
