Describe and explain the effect of substrate concentration on the rate of enzyme-controlled reactions
● As substrate conc. increases, rate of reaction increases
○ Substrate conc. = limiting factor (too few enzyme
molecules to occupy all active sites)
○ More Enzyme-substrate complexes form
● At a certain point, rate of reaction stops increasing / levels off
○ Enzyme conc. = limiting factor
○ As all active sites saturated / occupied (at a given time)
