Question

When temperature increases oxyhaemoglobin curve will become?

Answer 1

Oxyhaemoglobin curve:

1. Oxyhaemoglobin curve is also known as the oxygen–hemoglobin dissociation curve, the oxyhemoglobin dissociation curve, or the oxygen dissociation curve.
2. Oxyhaemoglobin curve describes the relationship between the partial pressure of oxygen in blood measured in mmHg (x-axis) and the oxygen saturation in percentage (y-axis).
3. The hemoglobin's oxygen content increases as ${\mathrm{P}}_{{\mathrm{O}}_2}$ increases until the maximum capacity is reached.

Effect of temperature on oxyhemoglobin curve:

1. An increase in temperature shifts the Oxyhaemoglobin curve to the right whereas a decrease in temperature shifts the Oxyhaemoglobin curve to the left.
2. Increasing the temperature makes denatures or cleaves the bond between oxygen and hemoglobin which increases the amount of oxygen and hemoglobin and decreases the concentration of oxyhemoglobin.
3. Higher temperature makes the dissociation of oxygen from oxyhemoglobin.
