Why can ATP not be stored in excess? Ask Question 13. 3 ... If we were to try to store enough ATP for say an hour the costs would be large. This back of the envelope calculation (see section 3.8) shows that 1 day of ATP is 64.5kg for a 2800 kcal a day energy intake. Approximately equal to body weight.
This is a good question to explore in detail because we can learn a lot about fuel metabolism and why we are designed the way we are. First, I want to dispense with this gee-whiz statistic that we synthesize 60 kg of ATP/day. This is a way to lie ...
In short: stored ATP, glycogen and creatine phosphate. Muscle and liver cells have a high capacity for glycogen storage because they require fast access when the need for it arises. These glycogen molecules are usually polymerized and precipitate...
Adenosine triphosphate (ATP) is a complex organic chemical that provides energy to drive many processes in living cells, e.g. muscle contraction, nerve impulse propagation, and chemical synthesis.Found in all forms of life, ATP is often referred to as the "molecular unit of currency" of intracellular energy transfer. When consumed in metabolic processes, it converts either to adenosine ....
W ithout question, the body's most important molecule, from an energy producing standpoint, is ATP (Adenosine Triphosphate: an adenine nucleotide bound to three phosphates, manufactured in the mitochondria).. In fact, every cell in our body, stores, and uses energy, biochemically, through ATP, and on this basis ATP could be considered a universal currency of biological energy.
But, to be fair, the question asked how much ATP is being consumed, not how much ATP is in the body. Based on a basal level of 380 litres of O2, that would consume about 65 kg of ATP per day for the average person. For a marathon runner it would be 300 - 400 kg of ATP on that day. for an ironman compeditor it would be on the order of 1 tonne.
Adenosine triphosphate (ATP) is considered by biologists to be the energy currency of life. It is the high-energy molecule that stores the energy we need to do just about everything we do. It is present in the cytoplasm and nucleoplasm of every cell, and essentially all the physiological mechanisms that require energy for operation obtain it ...
Energy is stored in ATP just like a battery when a cell has energy available, it can store small amounts of it by adding a phosphate group to ADP molecules.

It's limited though because the store of creatine phosphate is small. (Normally the supply of creatine phosphate is re-stocked by oxidative metabolism via the ATP produced by the citric acid cycle, but during intense exercise there is not enough time to do this so the stock is burned in 20-25 sec.)
