Answer:
The answer is C. BPG aids oxygen delivery to tissues by increasing the affinity of myoglobin for oxygen
Explanation:
The 2,3-bisphosphoglycerate (BPG) which can also be referred to as the 2,3 - di phosphoglycerate , is being produced by the red cells and has the ability to deoxygenate hemoglobin. This is because , his accumulation results to a decrease in the affinity for oxygen, this means that , it will convert hemoglobin to a low oxygen affinity state.
In this case, comparing the options given, it will be concluded that, 2,3 -biphosphoglycerate {BPG} does not aids the delivery of oxygen to tissues, but decreases the affinity of oxygen, which deoxygenate hemoglobin, and causes the concentration of the carbon dioxide to increase.
