In cell respiration oxygen is involved as a reactant along with organic fuels and will produce water carbon dioxide as well as ATPs main energy products. Cellular Respiration Definition Cellular respiration is the process through which cells convert sugars into energy.
Organisms that do not depend on oxygen degrade foodstuffs in a process called fermentation.
Cellular respiration and respiration. The key difference between respiration and cellular respiration is respiration is the entire process which consists of two phases physiological respiration and cellular respiration whereas cellular respiration is only one phase of the respiration process where glucose is converted to energy in the presence of oxygen in cellular level. Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules or nutrients into adenosine triphosphate ATP and then release waste products. The reactions involved in respiration are catabolic reactions which break large molecules into smaller ones releasing energy because weak high-energy bonds.
Internal repsiration is gas exchange between blood and tissues. To create ATP and other forms of energy to power cellular reactions cells require fuel and an electron acceptor which drives the chemical process of turning energy into a useable form. Cellular respiration is the process of breaking down complex organic molecules that are rich in potential energy into a lower energy waste product catabolic process at the cellular level.
Cellular respiration begins when electrons are transferred from NADH and FADH 2 made in glycolysis the transition reaction and the Krebs cyclethrough a series of chemical reactions to a final inorganic electron acceptor either oxygen in aerobic respiration or non-oxygen inorganic molecules in anaerobic respiration. Cellular respiration is oxidative metabolism of glucose which takes place in mitochondria and in the cell. 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.
