15 sty 2021 · Learn how cells convert sugars into energy using oxygen or other electron acceptors. Find out the equation, steps and products of aerobic and anaerobic respiration.
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.
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.
25 sie 2020 · Aerobic respiration is the process by which organisms use oxygen to turn fuel, such as fats and sugars, into chemical energy. In contrast, anaerobic respiration does not use oxygen. Respiration is used by all cells to turn fuel into energy that can be used to power cellular processes.
17 mar 2022 · The TCA cycle and oxidative phosphorylation require oxygen, while glycolysis can occur in anaerobic conditions. Glycolysis is the initial breakdown of glucose to pyruvate, a three carbon structure, in the cytoplasm. The pyruvate then moves into the mitochondrial matrix where a transition step called pyruvate oxidation takes place.
Khan Academy provides an overview of the steps involved in cellular respiration, including glycolysis, pyruvate oxidation, the citric acid cycle, and oxidative phosphorylation.
Aerobic respiration requires oxygen. This is the reason why we breathe oxygen in from the air. This type of respiration releases a large amount of energy from glucose that can be stored as ATP. Aerobic respiration happens all the time in animals and plants, where most of the reactions occur in the mitochondria.
