A research study investigates a novel enzyme. It is found that increasing the substrate concentration significantly increases the reaction rate, but only up to a certain point, after which the rate plateaus. Adding more enzyme further increases the maximum reaction rate. This kinetic behavior is characteristic of which enzyme regulation model?
✓ Correct Answer: Option D
Michaelis-Menten kinetics describes enzymes that exhibit saturation at high substrate concentrations, reaching a Vmax. Increasing enzyme concentration directly increases Vmax by providing more active sites, consistent with the description.
