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)

Correct Answer: rp = rmax Cs/(Km+Cs)
