Question

8. Using LeChâtelier's Principal, describe how holding your breath lowers blood pHi HCO3 (g) H'(aa) H2CO3 (aq) CO2 (g) H2O + Step one, breath is held resulting in This results in: Which in turn results in: O, with each before the breath is held. The concentration of all reactants and products stays the same when assessing multistep To envision the system at equilibrium, consider someone breathing normally, removing 6 mm Hg C breath (lecture 17, page 7) even though co2 is leaving the system, since acid is generated as a byproduct of metabolism and we maintain a reserve of bicarbonate. Such a system is in a "steady state", an important consideration biochemical processes

Explanation / Answer

Breath is held resulting increase in Carbon dioxide(CO2) in the body

This results in backward shift of the reaction favouring formation of H+

Which in turn results in increase in concentration H+ and lowers in pH of blood
