ATP is a molecule with three phosphate groups attached to a DNA base (A). the third and second phosphate are often removed in chemical reactions and the energy released from breaking these bonds is carefully channelled to catalyse other chemical reactions in the cell.
ATP is also kept away from equilibrium of its chemical reaction, meaning in the cells there are many more molecules of ATP products made when phosphates are removed to give ADP or AMP:
ATP <-----> ADP + Phosphate
ATP <-----> AMP + Di phosphate (2 phosphates)
By the cell maintaining ATP at high concentrations and ADP and AMP at low concentrations the energy released from breaking ATP down to ADP or AMP is much larger than if there were equal amounts of ATP, ADP and AMP. This is why ATP is said to contain energy, like pushing a Bowling ball to the top of a hill and then letting it roll down ATP releases energy when it is turned into its products.
One molecule of glucose stores 90 times the amount of chemical energy than one molecule of ATP.
ATP contains two high-energy bonds. These bonds are found between the phosphate groups of the molecule and store energy that can be readily released for cellular processes.
Adenosine triphosphate (ATP) is a multifunctional nucleotide that is most important as a "molecular currency"of intracellular energy transfer. Adenosine diphosphate (ADP), a nucleotide, is an important part of photosynthesis and glycolysis. ADP can be converted into ATP and is also the low energy molecule. ATP is the breakdown of food molecules. ATP is high energy bond as compared to ADP. ATP has three phosphate bonds and ADP has two phosphate bonds. Rest of the structure is common to both.
Glucose contains chemical energy which is released when it is broken down during cellular respiration to produce ATP. Light energy is not stored in glucose.
ATP (adenosine triphosphate) has three phosphate groups attached, serving as the cell's primary energy carrier. When one phosphate group is cleaved off, ATP becomes ADP (adenosine diphosphate), releasing energy that cells can utilize for various functions. ADP can be converted back into ATP through cellular respiration processes.
it stores energy in the bonds between its phosphate groups. When these bonds are broken during cellular processes, energy is released for use by the cell. This makes ATP a high-energy molecule essential for various biological activities.
ATP contains three phosphate groups. The third phosphate group (the outermost one) is called the alpha phosphate. The breaking of this phosphate bond is accompanied by the release of a large amount of energy which can be used to drive key steps in metabolic reactions. With the removal of alpha phosphate, the remainder molecule is ADP
Energy is released, which can be used to drive cellular processes. ATP hydrolysis is a key reaction in providing energy for metabolic pathways and cellular functions.
High energy bonds in ATP are found between the second and third phosphate groups. This bond is called a phosphoanhydride bond and contains a large amount of chemical energy due to the repulsion between the negatively charged phosphate groups.
Cells that secrete large amounts of substances via active transport need a large amount of energy in the form of ATP in their cytoplasm. Active transport mechanisms require energy to move molecules across the cell membrane against their concentration gradient. This energy is generated in the cell through processes such as cellular respiration.
Glucose is an example of an energy-rich compound as it can be broken down in cells through cellular respiration to produce a large amount of ATP, which serves as the main energy currency of the cell.
A high-energy phosphoanhydride bond joins the phosphates of ATP. This bond stores a large amount of energy that can be released when broken through hydrolysis.
Effective cellular respiration releases a large amount of energy (ATP). In order for effective cellular respiration to occur, oxygen must be present in the second stage of cellular respiration, the Krebs Cycle. If after the first stage of cellular respiration, glycolysis, there is no oxygen present, then ineffective cellular respiration occurs and the process is carried out by fermentation. Fermentation is an anaerobic process that results in the formation of ethyl alcohol or lactic acid and the cycle produces a net ATP gain of 2, whereas the net ATP gain of effective cellular respiration is 36 ATP molecules. Therefore cellular respiration in the presence of oxygen deals out a large amount of energy, but if not in the presence of oxygen, it deals out a small amount of energy.

ATP contains energy in the chemical bonds between its phosphate groups.
One molecule of glucose stores 90 times the amount of chemical energy than one molecule of ATP.
ADP has less potential energy than ATP has. In fact, there are 7.3 kc less energy in ADP than in ATP.
