Involved in the mechanics of breathing; The muscles involved in this type of breathing are the diaphragm, the external intercostal muscles, and the accessory respiratory muscles (activated when respiration increases significantly) Forced Exhalation.
Nitro- a combining form (used also adjectively) designating certain compounds of nitrogen or of its acids, as nitrohydrochloric, nitrocalcite; also, designating the group or radical NO2, or its compounds, as nitrobenzene
The Chemical Process. In nitrification, ammonia is first converted to nitrites (NO2-) and then to nitrates. The initial step of this process, known as nitritation, involves a type of bacteria called nitrosomonas. During nitritation, nitrosomonas convert NH3 (ammonia) into NO2 (nitrogen dioxide). The chemical equation for this process is NH3 + 1.5 O2 --> NO2- + H+ + H20. The second part of the nitrification process is called nitration. Nitration uses the enzyme nitrite oxidoreductase (NOR) to complete the nitrification process. The chemical equation for this reaction is NO2- + Â½ O2 --> NO3.
