Beginning Questions:
Carbon dioxide is formed during cellular respiration and then diffuses out of cells into the interstitial fluid and then into the bloodstream. Most of the carbon dioxide is transported in our blood as bicarbonate. Write the chemical equation for the formation of bicarbonate and hydrogen ions from carbon dioxide and water below.
Under which of the following situations would the formation of bicarbonate and hydrogen ions be greater? Circle your answer.
