- A.
3,2 DPG
- B.
2,3 DPG
- C.
2,3 PEG
- D.
None of the above
Correct Answer
B. 2,3 DPGExplanation
2,3 DPG is necessary to enable hemoglobin to have a normal O2 affinity. 2,3 DPG is a small molecule that binds to hemoglobin and helps regulate its oxygen affinity. It is produced in red blood cells during glycolysis and acts as a negative allosteric regulator of hemoglobin's affinity for oxygen. By binding to hemoglobin, 2,3 DPG decreases its affinity for oxygen, allowing for efficient unloading of oxygen to tissues. Without 2,3 DPG, hemoglobin would have a higher affinity for oxygen, making it less likely to release oxygen to tissues.Rate this question:

Correct Answer
C. 50-100 bpmExplanation
The acceptable blood donor pulse is 50-100 bpm. This range indicates a normal resting heart rate, which is important for ensuring that the donor is in good cardiovascular health. A pulse rate below 50 bpm may indicate bradycardia, a condition where the heart beats too slowly, while a pulse rate above 100 bpm may indicate tachycardia, a condition where the heart beats too fast. Both conditions can be concerning for blood donation as they may indicate underlying health issues or physiological stress on the heart. Therefore, a pulse rate between 50-100 bpm is considered acceptable for blood donation.Rate this question:
