ATP is created by the movement of protons back into the mitochondrial matrix through complex V which is ATP synthase. The effect that electron transport has on oxidative phosphorylation is that the two processes are tightly coupled, stopping electron transport will ultimately stop oxidative phosphorylation.
ATP, NAD+, FAD, and water
i dont know.....f*** my test is in 1 hour!
Oxidative Phosphorylation [Chemiosmosis and ETC]
The mitochondria is the main site for Cellular Respiration, the process in which your cells convert sugars and oxygen into ATP, the universal energy. ATP is used throughout your entire body as a source of energy to perform its daily functions.
The Electron Transport process is the third process in cell respiration, it requires oxygen directly. The electron transport "chain" is a series of electron carriers in the membrane of the mitochondria. Through a series of reactions, the "high energy" electrons are passed to oxygen. In the process, a gradient is formed, and ultimately ATP (Adinosine triphosphate), an energy molecule is formed.Therefore this stage produces the most ATP.
Oxygen is NOT needed to produce ATP. This is only true for Oxidative Phosphorylation. Substrate Level Phosphorylation does not require ATP at all. While ATP can be produced without oxygen via a process called anaerobic respiration, aerobic respiration is a much more efficient means of ATP production. Aerobic respiration is the release of energy from glucose or another organic substrates in the presence of Oxygen. Strictly speaking aerobic means in air, but it is the Oxygen in the air which is necessary for aerobic respiration. Anaerobic respiration is in the absence of air. Aerobic respiration takes place in almost all living things. It is easy to get rid of the Carbon Dioxide and excess water; this is excretion (the removal of the toxic waste products of metabolism), and maximum energy is released from the glucose. Some organisms can respire in the absence of air: this is anaerobic respiration. This does not release so much energy and it produces much more toxic waste products. However, if Oxygen is not available, anaerobic respiration is better than nothing. When this happens in our muscles we produce lactic acid which gives you cramp.
oxidative phosphorylation in cellular respiration
oxidative phosphorylation
oxidative phosphorylation
ATP is produced by substrate level phosphorylation during glycolisis. There is no oxidative phosphorylation in fermentation since it's an anaeorobic respiration.
oxidative phosphorylation
The opposite of phosphorylation is dephosphorylation. Source: http://en.wikipedia.org/wiki/Dephosphorylation
Mitochondria
Oxidative phosphorylation is necessary for most metabolic function. It is highly efficient and the primary means by which ATP is produced, which provides the energy for metabolism.
Yes, Wikipedia does offer in depth information on Oxidative Phosphorylation. They break it down into many parts and have several diagrams to explain what it is.
Cell membrane
Oxidative phosphorylation occurs in order to produce energy in the form of ATP. It occurs after chemiosmosis, in which a concentration gradient of hydrogen ions is created in the mitochondria between the matrix and the intermembrane space. As the hydrogen ions flow across this gradient, ADP and Pi are combined and ATP is produced. Hope this helps!
Because it is oxidative and depends mainly on oxidative phosphorylation for energy.
