NEETZoologyBreathing and Exchange of Gases
What conditions shift the graph to the right?
Options
- AIncreased pH
- BDecreased pCO2
- CDecreased temperature
- DIncreased H+ concentration
Correct answer
A. Increased pH
Step-by-step solution
This curve is called the Oxygen dissociation curve (Figure 17.5) and is highly useful in studying the effect of factors like , H+ concentration, etc., on binding of O2 with haemoglobin. In the alveoli, where there is high , low , lesser H+ concentration and lower temperature, the factors are all favourable for the formation of oxyhaemoglobin, whereas in the tissues, where low , high , high H+ concentration and higher temperature exist, the conditions are favourable for dissociation of oxygen from the oxyhaemoglobin
