When an enzyme is saturated with substrate it means the substrate concentration reaches a point at which none of the available active sites are free. Since the reaction rate is now determined by how fast the enzyme-substrate complex is converted to product, the reaction rate becomes constant- the enzyme is saturated.

Enzymes are not reactants and are not used up during the reaction. Once an enzyme binds to a substrate and catalyzes the reaction, the enzyme is released, unchanged, and can be used for another reaction. This means that for each reaction, there does not need to be a 1:1 ratio between enzyme and substrate molecules.

http://benchpartner.com/q/do-enzymes-act-better-under-acid-or-basic-ph WebEnzymes can be deactivated by a range of factors. Often, this happens because of changes in temperature or pH. Enzymes are picky. Each enzyme has a small range of temperatures and pH levels at which it works best. We call this optimum pH and optimum temperature. If either one falls out of range, the enzyme works much less efficiently.

Web7 apr. 2024 · Most enzymes act in pH between 6 and 8, a range that corresponds to the general acidic level of cells and blood.
