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.
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 ...
When the cell needs energy to do work, ATP loses its 3rd phosphate group, releasing energy stored in the bond that the cell can use to do work. Now its back to being ADP and is ready to store the energy from respiration by bonding with a 3rd phosphate group. ADP and ATP constantly convert back and forth in this manner.
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 ....
To avoid this, we have to switch to aerobic metabolism. We can do so by utilising protein, fat and carbohydrate metabolism for synthesising ATP and utilising the mitochondria (via the Krebs respiratory cycle) to generate abundant amounts of ATP without the waste products of anaerobic metabolism.
In tissues with high, short-term energy needs, like muscle, ATP is "stored" as creatine phosphate. The phosphate bound to creatine is high energy and is liberated from creatine in the form of ATP, via creatine kinase. Creatine kinase is sensitive to the immediate energy needs of the cell, namely creatine (unphosphorylated) and ADP levels.

What do the prefixes reveal about the chemical compostion of AMP, ADP, and ATP? stored between 2nd and 3rd phosphate, energy is transferred by removing 3rd phosphate and attaching it to another molecule that needs to do work (channel protein, muscle cell, sodium-potassium pump in a nerve cell)

If we have to recharge ADP back to ATP, why do we new ATP at all? Why jot just use the energy we get from food directly and skip the whole ...
During rapid, high-intensity exercise, your muscles use large amounts of energy in the form of a compound called adenosine triphosphate, or ATP. To allow you to keep working out, ATP stores must be replenished quickly. Muscles utilize both anaerobic and aerobic metabolism to produce ATP, but during fast-paced, ...
