Aug 6, 2021 · Respiration occurs in the cytosol and around the plasma membrane in prokaryotic cells. In eukaryotic cells, respiration takes place in the mitochondria, which is also considered as the powerhouse of the cells.. This process is very much similar to internal combustion of the car engine, wherein organic compounds and oxygen go in, while water and carbon dioxide comes out.
In physiology, respiration is the movement of oxygen from the outside environment to the cells within tissues, and the removal of carbon dioxide in the opposite direction to the surrounding environment.. The physiological definition of respiration differs from the biochemical definition, which refers to a metabolic process by which an organism obtains energy (in the form of ATP and NADPH) by oxidizing nutrients and releasing waste products. Although physiologic respiration is necessary to ...
Respiration is the process in which organisms exchange gases between their body cells and the environment. From plants and animals to prokaryotic bacteria, archaeans, eukaryotic protists, fungi, and animals, all living organisms undergo respiration.
Aug 20, 2019 · 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 ...
Jul 23, 2024 · Cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water. It includes glycolysis, the TCA cycle, and oxidative phosphorylation.
Oct 8, 2023 · Aerobic respiration is the process of turning food into a form of chemical energy cells can use. It requires oxygen. Aerobic respiration is a complex, multi-stage process that efficiently produces ATP, the primary energy currency for cells.
Typical eukaryotic cell. Cellular respiration is the process by which biological fuels are oxidized in the presence of an inorganic electron acceptor, such as oxygen, to drive the bulk production of adenosine triphosphate (ATP), which contains energy.Cellular respiration may be described as a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from nutrients into ATP, and then release waste products.. Cellular respiration is a vital ...

Respiration begins at the nose or mouth, where oxygenated air is brought in before moving down the pharynx, larynx, and the trachea.The trachea branches into two bronchi, each leading into a lung.Each bronchus divides into smaller bronchi, and again into even smaller tubes called bronchioles.At the end of the bronchioles are air sacs called alveoli, and this is where gas exchange occurs.
