Nоrmаl blооd pH is 7.35, which is slightly аlkаline. If you go out for a run cells will increase the rate of cellular respiration and make CO2 at a faster rate than usual. CO2 in the blood combines with water to form carbonic acid (H2CO3). Carbonic acid breaks apart into H+ (hydrogen) and HCO3- (bicarbonate). What affect will this have on blood pH? Would the amount of H+ in the urine increase or decrease in this case?
