A large proportion of oxygen is left unused in human blood even after its uptake by the body tissue is o2 neet prep
Answers
ANSWER:-
acts as a reserve during muscular exercises
Our tissue is able to utilise only 25% of O2 carried by the arterial blood. The venous blood is still 75% saturated with O2. This O2 acts as a reserve during muscular exercise.

The question is incomplete as it does not have the options which are:
1. Helps in releasing more O2 to the epithelium tissues
2. Acts as a reserve during muscular exercise
3. Raises the pCO2 of blood to 75 mm of Hg
4 Is enough to keep oxyhaemoglobin saturation at 96%
Answer:
2. Acts as a reserve during muscular exercise
Explanation:
The oxygen in blood is transported to the body parts attached to the hemoglobin protein in RBC in blood vessels.
The oxygen is absorbed by the cells and tissues depending on the difference in the partial pressure which shows that the how much oxygen is present.
If the oxygen is not utilized by the tissues it shows that the cell does not need enough oxygen and body is at rest but the body reserves some extra oxygen in the blood for some physical exercise if performed suddenly which requires the movement of the muscles and thus oxygen for production of ATP.
