During metabolism, the presence of excess substrate fails to restore the original reaction rate. The observation suggests the presence of

A. A non-competitive inhibitor
✓
B. A competitive inhibitor
C. Excess coenzyme
D. Product activation

📝 Explanation

Since excess substrate cannot overcome non-competitive inhibition, enzyme activity remains reduced. Competitive inhibition would be reversed by increasing substrate concentration. Concept tested: Differentiating inhibitor types.

📖 Additional Information

  • A non-competitive inhibitor
  • A competitive inhibitor
  • Excess coenzyme
  • Product activation
