Respuesta :

At the start of cellular respiration, energy is stored in the bonds of glucose molecules, but at the end of cellular respiration, energy is stored in the bonds of ATP molecules. 

Answer:

Glucose - ATP

Explanation:

During the glycogen synthesis process, energy from food is stored in the glucose bonds present.

Later, during the breakdown of sugar, ATP (adenosine triphosphate) bonds break down, and then the energy that was stored in the bonds is released to the metabolic processes.
