What process adds the third phosphate to an ADP molecule?
The third phosphate group releases energy using hydrolysis. Then, the third phosphate group will be released too. The adenosine diphosphate (ADP) will absorb the energy back to regain the third phosphate group.
How does ATP release its energy?
ATP works by losing the endmost phosphate group when instructed to do so by an enzyme. This reaction releases a lot of energy, which the organism can then use to build proteins, contact muscles, etc. The reaction product is adenosine diphosphate (ADP), and the phosphate group either ends up as orthophosphate (HPO4) or attached to another molecule (e.g. an alcohol). Even more energy can be extracted by removing a second phosphate group to produce adenosine monophosphate (AMP). When the organism is resting and energy is not immediately needed, the reverse reaction takes place and the phosphate group is reattached to the molecule using energy obtained from food or sunlight. Thus the ATP molecule acts as a chemical 'battery', storing energy when it is not needed, but able to release it instantly when the organism requires it.
What does ATP stand for and what are its structural components?
Adenosine TriPhosphate, it consists of one adenosine molecule (the same adenosine as the nucleotide base in DNA and RNA) to which three phosphate groups are attached. It is used for cellular energy storage, this energy is extracted when needed by the cell by removing one phosphate group leaving ADP or Adenosine DiPhosphate. Other cellular systems using either aerobic or anaerobic metabolism to supply energy reattach a phosphate group to ADP making ATP to rebuild the reserves.
Formula for synthesis and degradation of ATP?
Making ATP: ADP + P + energy (comes from cellular respiration) ----> ATP + water Using ATP: ATP + water ------> ADP + P + energy (this energy is used by cells to do work) The P stands for a phosphate group, not the element phosphorous.
Can water be purified using detergents?
phosphate :)

Using the analogy of a battery how is ATP stored and released from ATP?
ATP (with 3 Phosphate Groups) would be the full charged battery. ADP (with 2 Phosphate Groups) would be the partially charged battery. To release energy, the bond between the 2nd and 3rd phosphate group is released. To store energy, a bond is made between the 2nd and 3rd phosphate group.
Why does removing a phosphate group from the triphosphate tail in a molecule of ATP release energy?
Chemically it doesn't. Biologists get sloppy in these areas. Only the completion of a bond releases energy. So, when something is phosphorylated with that phosphate group then an energetic conformational/chemical/physical change takes place using the energy of that bonding.
What organic compounds or nutrients in main source of ATP?
ATP is manufactured in every aerobic cell by using energy from metabolizing sugars with oxygen to add a phosphate group to ADP. Anaerobic cells also produce ATP from a phosphate group and ADP, but the energy comes from reactions not involving oxygen (e.g. sulfur might be an option).

What does atp supply that fuels cell activities?
ATP stands for adenosine Di-phosphate. When cells need energy,then ATP can be broken down using water to release energy. It contain tri phosphate (three phosphate groups )

How ATP transfer its energy?
Nearly always, the phosphate is directly transferred to another molecule. Then, a chemical reaction that consumes energy is carried out in such a way that it is coupled to the release of the phosphate, so that the overall reaction releases energy and can proceed spontaneously (with catalytic help from enzymes, of course). For example, assembling a polymer often begins by phosphorylating the monomers, using ATP. Then, an enzyme positions everything so that a hydroxyl on one monomer can attack the other monomer and displace the phosphate. The phosphate is such a great leaving group that the attack becomes very favorable.

How do cells store and use energy with ATP and ADP molecules?
ATP is adenosine triphosphate, and there are high-energy bonds between the phosphate bonds. ATP has three phosphates branching off of the adenosine in one triphosphate arm. To tap into the energy in ATP cells simply have to break the bonds using enzymes. After the ATP is broken down it will be turned into ADP (adenosin diphosphate)+phosphate, with no bond between the diphosphate and the leftover phosphate.
What is a coupled reaction using as an example the conversion of glucose to glucose-6-phosphate?
A coupled reaction is two reactions that occur together. One reaction is necessary for the other to occur.The conversion of glucose to glucose-6-phosphate is a good example. The first step that the cell takes in glycolysis (the beginning of the cellular respiration of glucose) is to convert glucose into glucose-6-phosphate. This phosphorylation requires an energy input, and therefore will not occur spontaneously.In the cell, both the necessary energy and the phosphate group are provided by a molecule of ATP. The free energy released by the conversion of ATP into ADP and a phosphate ion (Pi) is far greater than the energy required for the phosphorylation of glucose, and so, when the two reactions are coupled together, the phosphorylation of glucose goes ahead.To couple these reactions a hexokinase is required. This enzyme needs magnesium as a cofactor.
Living things grow and develop using energy and raw materials they obtain from the?
WE take food as a source of energy.Inside the body this food is oxidized.If we talk about the cellular level the oxidativephosphorylation takes place in the mitochondria which traps the energy releases into ATP(adenosine triphosphate).When energy is needed ATP converts into ADP losing its phosphate group and releasing energy for cellular activity etc.Actually ATP is the energy currency of the cell.
