Which of the following statements regarding coenzymes and prosthetic groups of enzymes is not true?

Options

  1. ABoth are required for enzyme action
  2. BBoth can be separated from enzyme by dialysis
  3. CBoth are organic compounds
  4. DBoth are not polypeptides

Correct answer

B. Both can be separated from enzyme by dialysis

Step-by-step solution

The term prosthetic group is used as the non-protein moiety tightly binds (covalently) with the apoenzyme. The coenzyme can be separated by dialysis from the enzyme while the prosthetic group cannot be, as coenzyme is not bound with apoenzyme tightly.
