Title: How does enzyme activity change as substrate concentration decreases? Post by: zzwChris on Jun 4, 2012 Explain on a molecular level.
I dont know if im right: a decreases in substrate conc -> decrease in enzyme activity due to decreased collisions?? Thanks!

If you are already familiar with Michaelis-Menten plot, you can easily see the relationship there. Less substrate = lower reaction velocity.
