Now this means that the competitive inhibitor and substrate are competing, they are in a RACE, for the active site, so adding more substrate just ups the chances that substrate binds to the active site rather than the inhibitor.

WebThe inhibition can be overcome with an increase in [S], so you can still reach Vmax (no changes to Vmax) if the [S] is high enough. Since you need more S to reach Vmax, you need more S to reach Vmax/2, aka increase in Km What is the hallmark of the lineweaver-burk plot for competitive inhibition?
