8. During an investigation, two reaction mixtures contain equal amounts of enzyme. Only one contains a competitive inhibitor. The mixture showing the greater increase in reaction rate after adding excess substrate is

A. The mixture containing the competitive inhibitor
✓
B. The mixture without enzyme
C. The mixture containing a non-competitive inhibitor
D. The mixture containing irreversible inhibitor

📝 Explanation

Excess substrate successfully competes with a competitive inhibitor, increasing enzyme activity. This effect is not observed with non-competitive or irreversible inhibitors. Concept tested: Experimental reasoning.

📖 Additional Information

  • The mixture containing the competitive inhibitor
  • The mixture without enzyme
  • The mixture containing a non-competitive inhibitor
  • The mixture containing irreversible inhibitor

Excess substrate successfully competes with a competitive inhibitor, increasing enzyme activity. This effect is not observed with non-competitive or irreversible inhibitors. Concept tested: Experimental reasoning.
