Question

if an external stimulus is acting to make the blood more acidic, what chemical or ion is being generated in the bloodstream and needs to be neutralized?

Answer 1

Answer:

While in the blood, bicarbonate ion serves to neutralize acid introduced to the blood through other metabolic processes (e.g. lactic acid, ketone bodies); likewise, any bases (e.g. urea from the catabolism of proteins) are neutralized by carbonic acid (H2CO3).
