Question

which step of respiration involves combustion - external or internal? Discuss the conditions required for combustion in detail.​

Answer 1

Answer:

Respiration is the process in which organisms exchange gases between their body cells and the environment. From prokaryotic bacteria and archaeans to eukaryotic protists, fungi, plants, and animals, all living organisms undergo respiration. Respiration may refer to any of the three elements of the process.

First, respiration may refer to external respiration or the process of breathing (inhalation and exhalation), also called ventilation. Secondly, respiration may refer to internal respiration, which is the diffusion of gases between body fluids (blood and interstitial fluid) and tissues. Finally, respiration may refer to the metabolic processes of converting the energy stored in biological molecules to usable energy in the form of ATP. This process may involve the consumption of oxygen and production of carbon dioxide, as seen in aerobic cellular respiration, or may not involve the consumption of oxygen, as in the case of anaerobic respiration.
