Question

Which of the following statements about 2,3-bisphosphoglycerate (BPG) binding is FALSE?

Answer 1

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.

Answer 2

Answer:

The answer is C: BPG aids oxygen delivery to tissues by increasing the affinity of myoglobin for oxygen.

Explanation:

2,3-Bisphosphoglycerate (2,3-BPG) or BPG controls the affinity for haemoglobin to oxygen and not myoglobin. Myoglobin is a monomer, where as haemoglobin is a tetramer hence BPG cannot have an effect on myoglobin.
