What happens to a molecule that is phosphorylated? Best Answer: 'phosphorylated' means that a phosphate group has been attached to the molecule. if the molecule is a protein, phosphorylation can activate or deactivate the protein by changing the overall shape of the molecule. if it's ADP that has been phosphorylated, you've made ATP, the chemical that is used to store energy for cellular processes.

- When proteins become denatured, they lose there shape. This can happen in very high temperatures or environments more acidic than the protein is used to, etc. When this happens, it can no longer bind to its specific molecules or other proteins, and thus its function is impaired.

What is the difference between substrate level and oxidative phosphorylation? Oxidative phosphorylation is the metabolic pathway in which cells use enzymes to oxidize nutrients, thereby releasing energy which is used to produce adenosine triphosphate. In most eukaryotes, this takes place inside mitochondria. Almost all aerobic organisms carry out oxidative phosphorylation. This pathway is probably so pervasive because it is a highly efficient way of releasing energy, compared to alternative fermentation processes such as anaerobic glycolysis. During oxidative phosphorylat

Photophosphorylation (Cyclic and Non-cyclic) Cyclic Photophosphorylation The cyclic photophosphorylation also results in the formation of ATP molecules just like in non - cyclic photo phosphorylation. As the electrons move downhill in the electron transport chain, they lose potential energy and ATP molecules are formed in the same way as in mitochondria during respiration.

Polymerization of Nucleotides (Phosphodiester Bonds) When pyrophosphate is cleaved by the addition of water, a great deal of free energy is released, ensuring that the reverse process (hydrolysis of the phosphodiester bond to give free nucleotides) is very unlikely to occur.

10.2: Phosphorylation reactions - kinase enzymes For example, in many phosphoryl transfer reactions (such as the phosphorylation of glucose, which we used as an example in section 10.1D) the gamma (γ) phosphate of ATP is transferred to an organic acceptor, releasing ADP.

Oxidative Phosphorylation Oxidative phosphorylation is a redox reaction in which electrons are transferred from donors to acceptors. This redox reaction releases energy which is used to produce ATP. Both substrate level phosphorylation and oxidative phosphorylation involves formation of ATP. 2  But in substrate phosphorylation there is a direct transfer of phosphate group to Adenosine diphosphate to give adenoisine triphosphate and there is no direct transfer of phosphate group in oxidative phosphorylation.

ATP When one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and ATP is converted to adenosine diphosphate (ADP). Likewise, energy is also released when a phosphate is removed from ADP to form adenosine monophosphate (AMP).

- Substrate Level Phosphorylation. Donation of inorganic phosphate (Pi) from specific organic compounds to ADP to form ATP. Substrate-Level Phosphorylation is simply the enzymatic transfer of a phosphate group from an organic molecule to adenosine diphosphate (ADP) to form adenosine triphosphate (ATP). The production of ATP from ADP requires addition, via a condensation reaction, of a single phosphate (PO43-) to the latter.

- up vote 31 down vote. The phosphate group in NADPH doesn't affect the redox abilities of the molecule, it is too far away from the part of the molecule involved in the electron transfer. What the phosphate group does is to allow enzymes to discriminate between NADH and NADPH, which allows the cell to regulate both independently.

Cell Respiration ATP, or adenosine triphosphate, is formed after the binding of one phosphate molecule (phosphorylation) to one ADP (adenosine diphosphate) molecule. This is a process that stores energy in the produced ATP molecule.When ATP provides energy to the cellular metabolism, it releases one of its phosphate ions and ADP reappears. ADP can also release more phosphate ions and generate AMP (adenosine monophosphate) or even non-phosphorylated adenosine.hen ATP provides energy to the cellular metabolism, it releases one of its phosphate ions and ADP reappears.

Organic Compounds Essential to Human Functioning Phosphorylation is the addition of a phosphate (PO 4 3−) group to a protein or other organic molecule. Phosphorylation and its counterpart, dephosphorylation, turn many protein enzymes on and off, thereby altering their function and activity. Protein phosphorylation is one type of post-translational modification.

What is oxidative phosphorylation? Oxidative phosphorylation (or OXPHOS in short) is the metabolic pathway in which the mitochondria in cells use their structure, enzymes, and energy released by the oxidation of nutrients to reform ATP.his store of energy is tapped by allowing protons to flow back across the membrane and down this gradient, through a large enzyme called ATP synthase; this process is known as chemiosmosis. This enzyme uses this energy to generate ATP from adenosine diphosphate (ADP), in a phosphorylation reaction.

Post-translational modification Phosphorylation is a very common mechanism for regulating the activity of enzymes and is the most common post-translational modification. Many eukaryotic proteins also have carbohydrate molecules attached to them in a process called glycosylation, which can promote protein folding and improve stability as well as serving regulatory functions.
