[1] [2] In this type of respiration, oxygen serves as the terminal electron acceptor for the electron transport chain. [1] Aerobic respiration has the advantage of yielding more energy ( adenosine triphosphate or ATP ) than fermentation or anaerobic respiration , [ 3 ] but obligate aerobes are subject to high levels of oxidative stress .
Pulmonary function testing is a safe procedure; however, there is cause for concern regarding untoward reactions and the value of the test data should be weighed against potential hazards. Some complications include dizziness, shortness of breath, coughing, pneumothorax, and inducing an asthma attack. [13] [14]
Calculation of RER is commonly done in conjunction with exercise tests such as the VO 2 max test. This can be used as an indicator that the participants are nearing exhaustion and the limits of their cardio-respiratory system. An RER greater than or equal to 1.0 is often used as a secondary endpoint criterion of a VO 2 max test. [5]
In physiology, respiration is the transport of oxygen from the outside environment to the cells within tissues, and the removal of carbon dioxide in the opposite direction to the environment by a respiratory system. [1]
Maintenance respiration, the amount of cellular respiration required for an organism to maintain itself in a constant state; Respiration (physiology), transporting oxygen and carbon dioxide between cells and the external environment Respiratory system, the anatomical system of an organism used for respiration
Respiration rates may increase with fever, illness, or other medical conditions. [2] Inaccuracies in respiratory measurement have been reported in the literature. [3] One study compared respiratory rate counted using a 90-second count period, to a full minute, and found significant differences in the rates. [citation needed].
They gather mostly at the top because aerobic respiration generates more ATP than either fermentation or anaerobic respiration. 4: Microaerophiles need oxygen because they cannot ferment or respire anaerobically. However, they are poisoned by high concentrations of oxygen. They gather in the upper part of the test tube but not the very top.
Respiration is the reverse process and consumes organic carbon to produce inorganic carbon. Photosynthesis, and the biological pump, is dependent on the availability of inorganic nutrients and carbon dioxide. [7] Photosynthesis: 6 CO 2 + 6 H 2 O + light → C 6 H 12 O 6 + 6 O 2 Respiration: C 6 H 12 O 6 + 6 O 2 → 6 CO 2 + 6 H 2 O + energy
