24.
When an enzyme is functioning at Vmax, the rate of the reaction is limited by
the number of collisions between enzyme and substrate
the number of substrate molecules in the reaction
the concentration of the substrate
the rate at which the enzyme can convert substrate to product

25.
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)
