Energy is usually released from the ATP molecule to do work in the cell by a reaction that removes one of the phosphate- oxygen groups, leaving adenosine disphosphate (ADP). When the ATP converts to ADP, the ATP is said to be spent. Then the ADP is usually immediately recycled in mitochondria where it is recharged and comes out again as ATP.

∙ 10y agoFrom a thermodynamic point of view, the hydrolysis of ATP is exergonic (gives off energy, thermodynamically 'spontaneous'). This reaction can therefore be coupled with an endergonic (non-spontaneous) one. If the combined reaction is endergonic, the reaction will take place.
ADP-ATP is endergonic and B-C is exergonic
Yes, the Calvin cycle is endergonic because it uses ATP molecules rather than creates them.
It is b. endergonic because active transport uses ATP for energy.
The reactions which are coupled in aerobic respiration are known as endergonic reactions. Different amounts of ATP are produced in these reactions.
Yes
ADP-ATP is endergonic and B-C is exergonic
Describe the relationships among endergonic reactions, ATP hydrolysis and cellular respiration?
It provides energy coupling between exergonic and endergonic reactions.
Sodium/Potassium pumps is a good paired reaction. As the pumps are used ATP is broken down into ADP and Pi (exergonic) and 3 Sodiums are pumped out while 2 Potassiums are pumped in. (endergonic).
ATP
Releases energy. Exergonic.
