For an enzyme that follows Michaelis-Menten kinetics, what happens to the initial reaction velocity v as the substrate concentration [S] becomes extremely high ([S] gg K_M)?
- The velocity decreases due to substrate inhibition.
- The K_M of the enzyme increases proportionally with the substrate concentration.
- The velocity continues to increase linearly with substrate concentration.
- The velocity approaches V_max and follows zero-order kinetics.
