BIO NMDCAT Inhibitors
nmdcat.online July 13, 2026

During an experiment, the inhibitor binds at a site other than the active site without affecting substrate binding directly. The reaction rate decreases because

A. The enzyme undergoes a conformational change
✓
B. The substrate is chemically destroyed
C. The active site is permanently removed
D. The enzyme becomes a product

📝 Explanation

Non-competitive inhibitors alter the enzyme's shape, reducing catalytic efficiency without directly blocking substrate binding. Concept tested: Allosteric inhibition.

📖 Additional Information

  • The enzyme undergoes a conformational change
  • The substrate is chemically destroyed
  • The active site is permanently removed
  • The enzyme becomes a product
