      Using the cellular respiration diagram, indicate what deamination consists of.

       

       

      Deamination is the removal of the  groups (–NH2) within  matter. Once freed, they can give rise to  (NH3).

      What is the scheme and the correct name of the following reaction?

       

      • Organic material (C, H, O) + CO2 -> O2 + H2O + Energy. This chemical reaction is called reaction CO2.

      • Correct answer
        Wrong answer

      • Organic material (C, H, O) + O2 -> CO2 + H2O + Energy. This chemical reaction is termed cellular respiration.

      • Correct answer
