By dissociating into carbon dioxide and water
b)
By releasing hydrogen atoms
c)
By binding with hydrogen atoms
d)
By interfering with the creation of new acids
3.
What effect will an increased respiratory rate have on pH and why?
a)
It will cause pH to decline because less CO2 will be available to combine with water to form carbonic acid.
b)
It will cause pH to increase because less CO2 will be available to combine with water to form carbonic acid.
c)
It will cause pH to decline because more bicarbonate will combine with carbonic acid.
d)
It will cause pH to increase because more bicarbonate will combine with carbonic acid.
