Why is ATP not good for long term storage?
Firstly, storing too much ATP would increase the osmotic pressure of many cells to increase and cause entry and exit of molecules from cells. Moreover, ATP can be hydrolyzed in water which would disallow the body from performing long-term storage.
ATP is an excellent energy storage molecule to use as "currency" due to the phosphate groups that link through phosphodiester bonds. These bonds are high energy because of the associated electronegative charges exerting a repelling force between the phosphate groups.
The breakdown of glucose is how cells get their energy. ATP molecules cannot store more energy than is being released by the cells. In fact, ATP stores less energy than a molecule of glucose.
These data demonstrate that this ATP based system sensitively detects pure cells and organic contaminants with a strong degree of linear predictability. A limitation of the system is its inability to detect gram-negative bacteria efficiently because of incomplete cell lysis.
ATP is an unstable high-energy compound composed of 1 molecule of adenine, 1 molecule of ribose and 3 molecules of phosphate groups. Under the action of ATP hydrolase, it hydrolyzes the high-energy phosphate bond, generating ADP and Pi, to release energy.
Lithium-ion batteries are among the most promising choices for residential long-duration power storage. Some solar power installation companies began offering package deals where consumers could get panels and lithium-ion battery storage installed simultaneously.
Fats are the primary long-term energy storage molecules of the body. Fats are very compact and light weight, so they are an efficient way to store excess energy. A fat is made up of a glycerol, which is attached to 1 to 3 fatty acid chains.
All amino acids have both a carboxyl group and an amino group attached to a central carbon. ATP is the body's most important form of long-term energy storage.
Because it is stored in muscle cells phosphocreatine is readily available to produce ATP quickly. However it is only stored in limited quantities and therefore like our ATP stores it also runs out very quickly.
Muscle stores of ATP are limited. Once exercise has started, the demand for energy increases and the stored supply of ATP is used up in a couple of seconds. If continued muscular contraction is to take place, ATP has to be reformed from ADP once it has been used up.
What happens if too much ATP is produced?
When the amount of ATP is available in excess of the body's requirements, the liver uses the excess ATP and excess glucose to produce molecules called glycogen. Glycogen is a polymeric form of glucose and is stored in the liver and skeletal muscle cells.
ATP has three different phosphate groups, but the bond holding the third phosphate group is unstable and is very easily broken.
Energy from ATP
To carry out life processes, ATP is continuously broken down into ADP, and, like a rechargeable battery, ADP is continuously regenerated into ATP by the reattachment of a third phosphate group.
Neutral ATP solutions stored frozen are stable for at least one year. A refrigerated solution would be stable for at least one week. ADP is the first hydrolysis product formed, with additional hydrolysis leading to the formation of AMP.
- Shorter service life. While a flywheel storage device has around the same service life as the UPS, batteries generally need to be replaced several times over the same period.
- Higher maintenance requirement.
- HYDROELECTRIC PUMPING.
- COMPRESSED AIR.
- THERMAL STORAGE.
- HYDROGEN FUEL CELLS.
Glycogen is a polysaccharide that serves as a form of stored energy in animals and fungi. Glycogen is made and stored in the cells of liver and muscles that are hydrated with the four parts of water. It acts as the secondary long-term energy storage.
So, the correct answer is 'Fat'
If an animal needed to store energy for long-term use, but not be encumbered with the weight of extra tissue, then high-calorie fat molecules are the best molecules for storage. So, the correct answer is "high-calorie fat molecules".

ATP (adenosine triphosphate) stores more energy than ADP (adenosine diphosphate). ATP has three phosphate groups with high energy bonds located between each group. ADP has only two phosphate groups. ADP also has high energy bonds located between each group.
How long can stored ATP be used to run the muscle?
All muscle cells have a little ATP within them that they can use immediately – but only enough to last for about 3 seconds! So all muscle cells contain a high-energy compound called creatine phosphate which is broken down to make more ATP quickly.
These ATP stores last only a few seconds after which the breakdown of PC provides energy for another 5-8 seconds of activity. Combined, the ATP-PC system can sustain all-out exercise for up to 10-15 seconds and it is during this time that the potential rate for power output is at its greatest.
The ATP-PC System lasts for 6-10 seconds and is used during maximal power output exercises such as all-out effort sprints, jumps, 1RMs etc. It's the simplest energy production process, as it enables a fast muscle contraction. There is also no acidic by-product, which usually causes fatigue.
Phosphocreatine is also known as creatine phosphate and like existing ATP; it is stored inside muscle cells. Because it is stored in muscle cells phosphocreatine is readily available to produce ATP quickly. However it is only stored in limited quantities and therefore like our ATP stores it also runs out very quickly.
The main cellular role of ATP is as a "short term" energy transfer device for the cell.
ATP usually reaches high concentrations within cells, in the millimolar range. Nonetheless, because of the high rate of ATP-dependent processes, together with its low stability in water, ATP content could quickly be depleted if it were not immediately replenished by glycolysis and oxidative phosphorylation.
