photosinthesis
During the light reactions of photosynthesis, water is split to create free protons (hydrogen minus an electron) within the thylakoid. The increasing number of protons also transported across the thylakoid membrane by an electron transport system, establish a concentration gradient where many hydrogen are present inside the thylakoid, as compared to the number outside.
The diffusion (chemiosmosis) of these protons through the enzyme ATP synthase provides the energy needed to allow for the condensation reaction which fixes the third phosphate group onto the ADP molecule.

How are ADP and ATP energy wise different?
ATP is more energitic than ADP because ATP has 3 high energy phosphet bonds out of which 3rd phosphate bond have highest energy which is not present in ADP (2 phosphate bonds)
Does ADP store more energy than ATP?
no! atp stores more! :)
How is ATP different from ADP?
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.
What is the immediate source of energy to reform ATP into ADP molecules?
glucose
Why does ATP contains a large amount energy?
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.
Where does the energy add a phosphate group to ADP to form ATP come from?
Energy is needed to add a third phosphate group to ADP to make ATP. What is a cell's source of this energy?
How is ATP regenerated from ADP?
One molecule of ADP can be easily formed to make one form of ATP. All you need to do is add one phosphate group to the ADP and ATP is formed.ADP + P + energy --> ATPADP + P + energy --> ATP
How do ADP and ATP differ in amount of potential chemical energy?
ADP has less potential energy than ATP has. In fact, there are 7.3 kc less energy in ADP than in ATP.
What is the chemical equation for the resynthesis of ATP?
ATP ---> ADP + Pi + Energy it's a coupled reaction THIS ANSWER IS WRONG - IT IS BACKWARDS! IF YOU MAKE THE ARROW GO IN THE OPPOSITE DIRECTION, IT WOULD BE CORRECT.
How do ATP and ADP differ in amount of potential energy?
ADP has less potential energy than ATP has. In fact, there are 7.3 kc less energy in ADP than in ATP.
When ATP loses energy it is converted into?
ATP can't lose energy......... because it is energy.
When ATP is converted to ADP Where is the energy?
Usually energy in the body's obtained from converting ATP into ADP. However, glycolysis, the process of converting glucose to pyruvate, releases energy that turns ADP into ATP.
Where does the carbon come from in the CO2 that you breathe out?
The ATP stores energy in an organism. When it changes from ATP to ADP it is only the effect of how many phosphates there are in the two. When the organism is using ATP it uses a phosphate which then changes to ADP after it takes a one of the three phosphates to make it into two.
Where does atp come from in cellular respiration?
ATP comes from the breakdown of glucose. Breaking this molecule produces energy. The energy is trapped in the ADP molecule by adding a P(phosphate)to ADP This can happen in the cytosol or the mitrochrondia.
Cells get energy to build molecules from ADP and?
Cells get energy in general from the use of ATP. ADP is what results from the use of ATP.
What compound is formed when ATP releases energy?
When ATP releases energy, high energy phosphate is created. This phosphate will then go on to make more ATP or ADP.
What is needed to add a third phosphate group to ADP to make ATP?
ATP synthase
