View Explanation

  • Hemoglobin is an allosteric protein, i.e. binding of allosteric modulator to hemoglobin alter binding of other substrate or molecule (i.e. O2).
  • Phosphofructokinase I is an allosteric enzyme and is regulated allosterically in glycolysis. All enzymes (except for ribozymes) are proteins. So PFK-I is an allosteric protein.
