ANSWER
24- option C
- ie, both OXYGEN and 2,3-bisphosphoglycerate act as an allosteric effector of haemoglobin.
- ALLOSTERIC EFFECTORS are a molecule that binds to an enzyme and causes allosteric effects.
- >Positive allosteric effects involve "activation" of the enzyme - increasing its activity. >Negative allosteric effects involve "inhibition" of the enzyme - decreasing its activity.
- Oxygen release from hemoglobin (Hb) is regulated by the allosteric effector 2,3-bisphosphoglycerate.
- Oxygen itself act as both allosteric effector and substrate.
- Binding of oxygen enhances the attraction between substrate molecules and other binding sites leads to Positive allosteric modulation.
- Therefore, both OXYGEN and 2,3-bisphosphoglycerate act as an allosteric effector of haemoglobin.
