Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
An increase in CO2 causes a decrease in blood pH.
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -In the presence of an excess of CO2, there will be a shift to carbonic acid, ultimately causing the generation of hydrogen cations and bicarbonate anions. It is with this increased production of hydrogen ions that bodily pH will begin to decrease, causing acidosis from acidemia.

Detailed explanation-2: -When CO2 levels are high, there is a right shift in the reaction mentioned above. As a result, the concentration of H+ ions in the bloodstream rises, lowering the pH and introducing a state of acidosis. In contrast, when CO2 levels are low, there is a left shift in the reaction, resulting in an alkalotic state.

Detailed explanation-3: -CO2 is an acid managed by the lungs. As PaCO2 increases, the blood becomes more acidic and the pH decreases. As PaCO2 decreases, the blood becomes less acidic and the pH increases.
