WebWhen an enzyme binds its substrate, it forms an enzyme-substrate complex. This complex promotes the reaction’s rapid progression in one of many ways. On a basic level, … WebA diffusion-limited enzyme catalyses a reaction so efficiently that the rate limiting step is that of substrate diffusion into the active site, or product diffusion out. [2] This is also known as kinetic perfection or catalytic perfection.
