Given below are two statements about the oxygen dissociation curve....
Given below are two statements about the oxygen dissociation curve.
Statement (I): The relationship between HbO_2) is called oxygen dissociation curve.
Statement (II): Oxygen dissociation curve shifts towards the right due to decrease in H^+ concentration and decrease in temperature.
In light of the above statements, choose the most appropriate answer from the options given below.
Statement (I): The relationship between HbO_2) is called oxygen dissociation curve.
Statement (II): Oxygen dissociation curve shifts towards the right due to decrease in H^+ concentration and decrease in temperature.
In light of the above statements, choose the most appropriate answer from the options given below.
Options
- ABoth Statement (I) and Statement (II) are correct.
- BBoth Statement (I) and Statement (II) are incorrect.
- CStatement (I) is correct but Statement (II) is incorrect.
- DStatement (I) is incorrect but Statement (II) is correct.
Correct answer
C. Statement (I) is correct but Statement (II) is incorrect.
Step-by-step solution
Statement (I) is correct. The oxygen dissociation curve is a graphical representation of the relationship between the partial pressure of oxygen (p) and the percentage saturation of hemoglobin with oxygen. \\ \\ Statement (II) is incorrect. The oxygen dissociation curve shifts to the right when there is a decrease in oxygen affinity of hemoglobin. This occurs due to an increase in H^+ (pCO_2 concentration and a decrease in temperature would shift the curve to the left.
Answer: Statement (I) is correct but Statement (II) is incorrect.
Answer: Statement (I) is correct but Statement (II) is incorrect.
