Competitive inhibition occurs when an inhibitor:
Show answer and explanation
Correct answer: Competes with substrate for the active site
Competitive inhibitors structurally resemble the substrate and compete directly for binding at the active site. The inhibition is reversible and can be overcome by increasing substrate concentration; Vmax remains unchanged but Km increases.
