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)

Question: 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)
[A].

rp = rmax Cs/(Km+Cs)
[B].
rp= rmax CES/(Km+ CES)
[C].
rp = rmax Cs/(Km+CES)
[D].
rp = rmax Cs/(Km+Cp)

Answer: Option A
