∙ 14y agoThe reactions which are coupled in aerobic respiration are known as endergonic reactions. Different amounts of ATP are produced in these reactions.
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.
The synthesis and decomposition reactions are coupled in cells through the process of metabolism. There are chemical reactions that are used in this entire process.
The energy from the hydrolysis of ATP may be directly coupled to endergonic processes by the transfer of the phosphate group to another molecule. A key feature in the way cells manage their energy resources to do this work is energy coupling, the use of an exergonic process to drive an endergonic one. ATP is responsible for mediating most energy coupling in cells, and in most cases it acts as the immediate source of energy that powers cellular work.
Basically, the light-trapping reactions trap sunlight within them. The products of these reactions are glucose and chlorophyll. These products are coupled to the synthesis of carbohydrates because when carbohydrates are synthesized, glucose is created. Both reactions have a product of glucose. This is how they are related/coupled.
Energy carriers can be broken apart to power an endergonic reaction or assembled using energy from an exergonic reaction

Endergonic reactions are always coupling reactions. They will only occur where there is input of energy and they usually take place in a simultaneous manner.

A coupled reaction is a chemical reaction having a common intermediate in which energy is transferred from one side of the reaction to the other. Many things are made this way.
