The equation for the rate of product formation for simple enzyme reaction is given by (Where rmax, maximum reaction rate, Cs substrate concentration, Cp product concentration ES, CES enzyme-substrate concentration)

• rp = rmax Cs/(Km+Cs)
• rp= rmax CES/(Km+ CES)
• rp = rmax Cs/(Km+CES)
• rp = rmax Cs/(Km+Cp)
