Q10Q_{10}Q10 is a measure of the rate of change of a reaction when temperature is increased by 10∘C10^\circ\text{C}10∘C.
Q10Q_{10}Q10 is calculated using this formula:
Q10=rate at higher temperature÷rate at lower temperature Q_{10} = \text{rate at higher temperature} \div \text{rate at lower temperature} Q10=rate at higher temperature÷rate at lower temperatureAn enzyme reaction has a rate of 45 units/min45\text{ units/min}45 units/min at 35∘C35^\circ\text{C}35∘C and 18 units/min18\text{ units/min}18 units/min at 25∘C25^\circ\text{C}25∘C.
