Can someone describe oxidative phosphorylation?

Question

Not Wikipedia!

Can someone describe the process in common terms and as a conceptual piece in the entire mechanism of processing food and respiring?

Answer 1

Oxidative phosphorilation is the last pat of the process of aerobic respiration. The process occurs in the mitochondria and two main events occur:

1- The electron carriers (NADH and FADH2) coming from the previous steps (glycolisis and the krebbs cycle) go to the electron transport chain in the inter membrane space of the mitochondria. Then they release the electrons, but remember that the electron carriers were originally NAD+ and FAD+, so they took both an electron and a proton and became NADH and FADH2, so the protons go to the mitochondrial matrix. As the electrons flow trough the chain, protons are pumped upward, making a proton gradient. The The electrons keep "falling" in the chain until they reach the last acceptor: Oxygen.

2- That gradient will now induce the production of ATP in the ATP sinthase complex. The protons will fall down their concentration gradient, get inside the ATP sinthase complex and synthesize ATP.

Answer 2

Oxidative phosphorylation is a process that occurs inside a part of cells called mitochondria. Each mitochondrion has a special structure which enables it to produce ATP, and the process which goes on in order to manufacture this is called oxidative phosphorylation, because it involves phosphorylating ADP (to produce ATP) using oxidation reactions.

By building up a proton gradient across the inner membrane of a mitochondria, a series of complexes and something called coenzyme Q (collectively known as the electron transport chain) effectively manufacture the ATP.

Answer 3

Oxidative phosphorylation is the culmination of a series of energy transformations that are called cellular respiration or simply respiration in their entirety. First, carbon fuels are oxidized in the citric acid cycle to yield electrons with high transfer potential. Then, this electron-motive force is converted into a proton-motive force and, finally, the proton-motive force is converted into phosphoryl transfer potential. The conversion of electron-motive force into proton-motive force is carried out by three electron-driven proton pumpsNADH-Q oxidoreductase, Q-cytochrome c oxidoreductase, and cytochrome c oxidase. These large transmembrane complexes contain multiple oxidation-reduction centers, including quinones, flavins, iron-sulfur clusters, hemes, and copper ions. The final phase of oxidative phosphorylation is carried out by ATP synthase, an ATP-synthesizing assembly that is driven by the flow of protons back into the mitochondrial matrix. Components of this remarkable enzyme rotate as part of its catalytic mechanism. Oxidative phosphorylation vividly shows that proton gradients are an interconvertible currency of free energy in biological systems.

Answer 4

To make ATP, energy must be absorbed. This energy is supplied by the food we eat, and then used to synthsize two reducing agents, NADH and FADH2 that are needed to produce ATP. One of the principal energy-yielding nutrients in our diet is glucose (see structure in Table 1 in the blue box below), a simple six-carbon sugar that can be broken down by the body. When the chemical bonds in glucose are broken, free energy is released. The complete breakdown of glucose into CO2 occurs in two processes: glycolysis and the citric-acid cycle.

Answer 5

It is when red food coloring is inserted into the computer chip, then your computer blows up because you ask stpid nerdy Q's like this. Heres a Q 4 ya...whats a cow???

Answer 6

Well, first this happend and then that and after that it is all over

Answer 7

someone can, yes. but it isn't me. sorry

Answer 8

i don't know what da hack is that!
