Explain how coupling reactions allow a cell to capture the free energy of glucose oxidation rather than allow it to escape to the environment through heat

This reaction is endothermic, therefore the energy uptake will be the main pillar of metabolism, in addition, the phosphorylation energy will always be used for the cell, on the other hand, in the case of phosphorylation, reverse effects will be seen, and this is when a I play an enzyme called kinase.

On the other hand, the intake or capture of energy in the form of energy currency is understood as the medium GIVES energy to the cell, it captures it and is not exothermically released in the form of heat.

Explanation:

These processes happen because of it at postpondrial moments, where the insulin hormone is high and it is sought to phosphorylate glucose to retain it inside the cell so that it does not dissipate exothermically.

This is the mechanism by which the human generates energy reserves of complex carbohydrates such as glycogen.
